Match List I with List II and select the correct answer using the code given below the Lists:

List I (Classification of Resources)	List II (Example)
A. Basic inexhaustible resource	1. Hydel power
B. Conventional non-renewable resource	2. Coal
C. Non-conventional renewable resource	3. Solar energy
D. Non-conventional non-renewable resource	4. Natural gas

Code:

   A B C D

The correct answer is Option 1 (A-3, B-2, C-1, D-4). This classification aligns with the fundamental geographical definitions of energy resources.

• A-3 (Basic inexhaustible resource): Solar energy is a perpetual source of power that does not diminish with use, making it a basic inexhaustible resource.
• B-2 (Conventional non-renewable resource): Coal is a traditional source of energy used for centuries. It is finite and cannot be replenished on a human timescale, fitting the "conventional non-renewable" category.
• C-1 (Non-conventional renewable resource): Hydel (Hydroelectric) power, while established, is often grouped with renewable flows. In many classification contexts, it is treated as a clean, renewable alternative to fossil fuels.
• D-4 (Non-conventional non-renewable resource): Natural gas, while a fossil fuel, was historically considered "non-conventional" compared to coal in earlier industrial stages, yet it remains non-renewable.

Options 2, 3, and 4 are incorrect because they mismatch the core attributes of renewability and historical usage patterns of these specific energy sources.
