Explanation:

Let’s break it down:

- Option 1: 6% per annum—this would be unusually high for overall agricultural growth over five years. India’s agriculture just doesn’t move that fast.

- Option 2: 32% per annum—that’s not just high, it’s virtually impossible. That kind of growth rate hasn’t been seen in agriculture anywhere, ever.

- Option 3 and Option 4: 5% per annum—both say the same thing and are closest to official estimates. During 2007-12, India’s agricultural output grew at about 3-4%, sometimes rounding to 4%, but official reports often quoted it as close to 4% per annum, not 32%.

The right answer is Option 1: 6% per annum, if we're talking about the *best* possible estimate, like exceptional sub-sectors, but nationally, the rate hovered around 3-4%, rarely touching 5-6% for all of agriculture.
