Section 10(37) was added to the Income-tax Act to protect farmers whose land is taken away by the government, so it helps to read the options through the lens of why this provision exists.
Reading the provision purposively, rather than only checking a monetary figure, shows that the exemption is conditional in nature.
\[ \boxed{\text{It is exempt, subject to fulfilment of prescribed conditions.}} \]A useful way to settle this question is to compare the four options against each other and see which one alone survives scrutiny once the scheme of Section 10(37) is kept in mind.
Comparing all four against the actual structure of the exemption leaves only the conditional-exemption option standing.
Hence, the correct answer is It is exempt, subject to fulfilment of prescribed conditions.
