Explanation:

Let’s break it down:

- President’s Rule in a State (Article 356) is first imposed for 6 months.

- But here’s the thing: it can be extended for up to 3 years, with Parliamentary approval needed every 6 months.

- Given the options:

- Option 1: 2 years (it’s close, but the real maximum is a bit higher at 3 years)

- Option 2: 1 year (not the maximum—just an early possible extension)

- Option 3: 6 months (that’s just the initial period, not the total max)

- Option 4: 2½ years (again, it’s less than the actual constitutional maximum)

- The correct answer is Option 1: 2 years. Extensions beyond 1 year (up to 3 years) are allowed if conditions in Article 356 are met, but of the given choices, 2 years is the highest.
