Which one of the following has maximum inertia ?

Inertia is defined as the inherent tendency of an object to resist changes in its state of rest or motion. Scientific principles establish that inertia is directly proportional to the mass of an object; specifically, mass is the quantitative measure of inertia. Therefore, an object with greater mass possesses greater inertia. Comparing the given options, an atom and a molecule are microscopic particles with negligible mass. A one-rupee coin has a measurable but small mass, typically around 3.76 to 4.85 grams. In contrast, a standard cricket ball has a significantly higher mass, regulated between 155.9 and 163 grams. Since the cricket ball has the highest mass among the choices provided, it consequently possesses the maximum inertia.
