Which one of the following is the correct sequence of Union Territories of India in the increasing order of their area ?

1. Administrative Structure of India: States and UTs (basic)

Welcome to your first step in mastering Indian political geography! To understand how India is managed, we must look at Article 1 of the Constitution, which describes India as a 'Union of States'. However, the 'Territory of India' is a much broader concept than the 'Union of India'. While the Union includes only the States, the Territory of India encompasses three distinct categories: (a) the States, (b) the Union Territories (UTs), and (c) any acquired territories the government may take over in the future M. Laxmikanth, Union and Its Territory, p.53. As of today, India is comprised of 28 States and 8 Union Territories.

The primary difference between these two units lies in their relationship with the Central Government. States are members of the federal system; they possess their own governments and share power with the Centre as defined by the Constitution. In contrast, Union Territories are those areas that are under the direct control and administration of the Central Government. This is why they are often referred to as 'centrally administered territories' M. Laxmikanth, Union Territories, p.409. They are governed by the President, usually acting through an Administrator or a Lieutenant Governor.

Historically, the number and nature of these territories have shifted significantly. Many current states, such as Himachal Pradesh, Goa, and Manipur, actually started their journey as Union Territories before being 'elevated' to full statehood D. D. Basu, Administration of Union Territories and Acquired Territories, p.310. This administrative flexibility allows the Indian government to manage regions that might be too small to be states, or those that have unique cultural, strategic, or security requirements.

Feature	States	Union Territories
Relationship with Centre	Federal (shares power)	Unitary (direct Central control)
Administrative Head	Governor (Constitutional head)	President (through an Administrator/LG)
Legislative Power	Have their own legislatures	Most do not (except Delhi, Puducherry, J&K)

2. Constitutional Provisions: Article 1 and Schedule 1 (basic)

At the very heart of the Indian Constitution lies Article 1, which declares: "India, that is Bharat, shall be a Union of States." This choice of words is deliberate. As Dr. B.R. Ambedkar explained in the Constituent Assembly, the term 'Union' was preferred over 'Federation' to emphasize two critical points: first, that the Indian federation did not arise from a contract or agreement between independent states; and second, that the states have absolutely no right to secede from the Union Introduction to the Constitution of India, D. D. Basu, NATURE OF THE FEDERAL SYSTEM, p.57. This establishes India as an indestructible union of destructible states, ensuring national integrity against threats like regionalism or secessionism Indian Polity, M. Laxmikanth, Preamble of the Constitution, p.46. While Article 1 sets the principle, Schedule 1 acts as the 'address book' of the Constitution. It contains the specific names of all the States and Union Territories, along with their territorial extent. Whenever the map of India changes—whether through the creation of a new state like Telangana or the reorganization of Jammu & Kashmir—Schedule 1 must be amended to reflect the new reality. It is important to distinguish between the 'Union of India' and the 'Territory of India.' The former is a narrower term including only the States, while the latter is broader, encompassing everything under Indian sovereignty.

Term	Scope	Constitutional Status
Union of India	Only the States	Members of the federal system who share power with the Centre.
Territory of India	States + Union Territories + Acquired Territories	A wider geographical expression of Indian sovereignty.

Administrative changes, such as the merger of Dadra and Nagar Haveli with Daman and Diu or changes in state boundaries following international agreements (like the 100th Amendment Act, 2015 regarding the enclave exchange with Bangladesh), are all formalized through updates to this Schedule Introduction to the Constitution of India, D. D. Basu, TABLES, p.525.

3. Evolution of UTs: From 1956 to Present (intermediate)

To understand the evolution of Union Territories (UTs), we must start at the 1956 milestone. Before this, India had a complex four-fold classification of states (Part A, B, C, and D). Based on the Fazl Ali Commission recommendations, the States Reorganisation Act (1956) and the 7th Constitutional Amendment Act were passed. These landmark changes abolished the old classification and created a clean structure of 14 States and 6 Union Territories Indian Polity, M. Laxmikanth, Union and Its Territory, p.53. Originally, UTs were created for areas that were either too small to be states or had unique cultural and strategic importance that required direct Central administration.

Following 1956, the map of UTs evolved through two main processes: Acquisition and Statehood Upgrades. Territories formerly under Portuguese and French rule, such as Dadra and Nagar Haveli, Goa, Daman and Diu, and Puducherry, were integrated into India as UTs during the 1960s Introduction to the Constitution of India, D. D. Basu, TABLES, p.573. Over time, several UTs were "promoted" to full statehood as they gained political maturity and economic stability—examples include Himachal Pradesh (1971), Manipur, and Tripura (1972) Geography of India, Majid Husain, India–Political Aspects, p.15.

Today, the geographical profile of UTs varies drastically. In terms of land area, there is a massive range from the tiny coral islands of Lakshadweep (the smallest at ~32 sq km) to the sprawling Ladakh and Jammu & Kashmir. Between these extremes, we see a hierarchy where Chandigarh (114 sq km) and Puducherry (~479 sq km) are significantly smaller than the Andaman and Nicobar Islands (~8,249 sq km) Introduction to the Constitution of India, D. D. Basu, TERRITORY OF THE UNION, p.73.

4. Governance Models: Delhi, Puducherry, and Others (intermediate)

In the grand design of Indian federalism, Union Territories (UTs) occupy a unique space. Unlike States, which enjoy a share of sovereignty with the Union, UTs are units administered directly by the Central government. Under Article 239, every UT is administered by the President through an 'Administrator' (often titled Lieutenant Governor in some territories). However, the Constitution allows for a 'hybrid' model where certain UTs are granted their own Legislative Assemblies and Councils of Ministers, bridging the gap between a pure administrative unit and a self-governing state M. Laxmikanth, Indian Polity, Union Territories, p.412.

The two primary examples of this hybrid model are Puducherry and Delhi. While Puducherry was the first to receive a legislature (under Article 239A), Delhi was granted a special status via the 69th Constitutional Amendment Act of 1991, which inserted Article 239AA. This redesigned the territory as the National Capital Territory (NCT) of Delhi. Unlike a full State, the Delhi Assembly's power is restricted: it can legislate on State List matters, but Public Order, Police, and Land remain under the exclusive domain of the Central Government M. Laxmikanth, Indian Polity, Union Territories, p.412.

Beyond governance, these territories vary wildly in their physical geography. For instance, while Lakshadweep is the smallest UT at roughly 32.62 sq km, others like the Andaman and Nicobar Islands are vast, covering over 8,000 sq km D. D. Basu, Introduction to the Constitution of India, Territory of the Union, p.73. Understanding this mix of administrative control and geographic scale is crucial for mastering Indian political geography.

Feature	NCT of Delhi	Puducherry	Other UTs (e.g., Chandigarh)
Legislature	Yes (70 members)	Yes (30 elected)	No (Direct Central Rule)
Administrator	Lieutenant Governor	Lieutenant Governor	Administrator / LG
Excluded Powers	Police, Land, Public Order	None specifically excluded	N/A (Center holds all)

5. Recent Reorganisation: J&K and Dadra-Daman Merger (exam-level)

In recent years, India's political map has undergone significant structural changes, moving away from a long-standing status quo. The most transformative shift occurred via the Jammu and Kashmir Reorganisation Act, 2019. This Act bifurcated the erstwhile State of Jammu and Kashmir into two distinct Union Territories: Jammu and Kashmir (with a Legislative Assembly) and Ladakh (without a legislature). While the bill received Presidential assent on August 9, 2019, the reorganization officially came into effect on October 31, 2019—a date chosen to coincide with the birth anniversary of Sardar Vallabhbhai Patel Indian Constitution at Work, NCERT Class XI, FEDERALISM, p.171.

The creation of Ladakh as a separate Union Territory addressed decades of regional aspirations. The region is characterized by a vast geographical area, sparse population, and extremely difficult terrain, making direct central administration a more viable path for its development Laxmikanth, M. Indian Polity, Union Territories, p.410. Furthermore, the reorganization led to a massive legal overhaul: 106 Central Acts became applicable to the new UTs, while 153 state laws were repealed to integrate the region fully with the national legal framework Introduction to the Constitution of India, D. D. Basu, Jammu and Kashmir, p.299.

Shortly after the J&K reorganization, the government addressed administrative fragmentation in Western India. In January 2020, the two separate Union Territories of Dadra and Nagar Haveli and Daman and Diu were merged into a single entity named Dadra and Nagar Haveli and Daman and Diu. This was done primarily to improve administrative efficiency and reduce the cost of governance Laxmikanth, M. Indian Polity, Union Territories, p.410. These combined changes mean that as of 2020, India transitioned from 29 States and 7 UTs to 28 States and 8 UTs.

Feature	UT of Jammu & Kashmir	UT of Ladakh
Legislature	Provided with a Legislative Assembly	No Legislative Assembly
Districts	Multiple (e.g., Srinagar, Jammu)	Kargil and Leh

6. Comparative Area and Geographical Statistics of UTs (exam-level)

To master the political geography of India, one must appreciate the stark contrasts in the physical scale of our Union Territories (UTs). While we often group them together, their areas range from tiny coral atolls to massive Himalayan landscapes. Historically, the Andaman and Nicobar Islands held the title of the largest UT, but the Jammu and Kashmir Reorganisation Act of 2019 fundamentally redrew this map. Today, Ladakh stands as the largest UT by area, followed by Jammu & Kashmir, both of which are significantly larger than any other UT. Indian Polity, M. Laxmikanth (7th ed.), Union and Its Territory, p.53 Among the smaller UTs, there is a specific hierarchy that frequently appears in competitive exams. Lakshadweep is the smallest, covering a mere 32.62 sq km. It is followed by Chandigarh (approx. 114 sq km) and Puducherry (approx. 479 sq km). A common point of confusion for students is the comparison between Chandigarh and Puducherry; despite Chandigarh being a major city, Puducherry is physically larger because its territory is spread across four non-contiguous districts (Puducherry, Karaikal, Mahe, and Yanam) in three different states. Geography of India, Majid Husain (9th ed.), Cultural Setting, p.73 When we look at geographical statistics beyond just area, population density provides a different perspective. For instance, while the NCT of Delhi is mid-sized in terms of area (approx. 1,483 sq km), it has the highest population density in the country, far exceeding states like Bihar or West Bengal. Geography of India, Majid Husain (9th ed.), Cultural Setting, p.73 In contrast, the larger UTs like Ladakh and the Andaman & Nicobar Islands have much lower densities due to their rugged terrain and forest cover. INDIA PEOPLE AND ECONOMY (NCERT 2025 ed.), Population: Distribution, Density, Growth and Composition, p.3

Comparison of UT Areas (Approximate)

Union Territory	Approx. Area (sq km)	Key Geographic Feature
Ladakh	59,146	High-altitude cold desert
Andaman & Nicobar	8,249	Volcanic/Tectonic Archipelago
NCT of Delhi	1,483	Yamuna Floodplains/Aravalli Ridge
Puducherry	479	Scattered Coastal Enclaves
Lakshadweep	32	Coral Atolls

7. Solving the Original PYQ (exam-level)

Now that you have mastered the foundational concepts of India’s administrative geography, this question tests your ability to apply spatial scale and territorial hierarchy. In your recent modules, you explored how Union Territories are managed differently based on their size and strategic importance. To solve this, you must synthesize your knowledge of geographical distribution—moving from tiny coral atolls to large oceanic archipelagos. This isn't just about memorizing numbers; it's about visualizing the physical map of India and recognizing the relative proportions of its constituent parts as described in the Introduction to the Constitution of India, D. D. Basu (26th ed.).

The reasoning follows a logical bottom-up approach. Start by identifying the smallest unit: Lakshadweep, which consists of just 32 sq km of land. Next, compare the two "city-based" UTs; Chandigarh is a planned urban center of roughly 114 sq km, whereas Pondicherry (Puducherry) is larger (479 sq km) because it spans four non-contiguous districts across different states. Finally, the Andaman and Nicobar Islands stand apart as a massive chain covering over 8,000 sq km. This progression leads us directly to the correct answer, Option (C): Lakshadweep - Chandigarh - Pondicherry - Andaman and Nicobar Islands.

UPSC often uses relative size traps to confuse candidates. Option (B) and (D) are classic examples where the extreme ends (smallest or largest) are misplaced to test your attention to detail. A common pitfall is swapping Chandigarh and Pondicherry; because both are perceived as urban enclaves, students often forget that Pondicherry’s multi-district layout gives it a significantly larger total land area than the single city-territory of Chandigarh. Always double-check the direction of the order—increasing versus decreasing—as misreading the prompt is a frequent source of "silly mistakes" in the exam hall.
