According to Kumar (1998), in which kind of region did the most unequ…

The correct answer is Option (4) → Regions of assured irrigation needing intensive cultivation

Option (1) Regions where the Brahmins were the major landowners — Incorrect. Brahmins were in most areas not major landowners. They stood outside the agrarian structure, though they were part of rural society, so Kumar does not link the sharpest inequality to them.

Option (2) Dry regions depending on uncertain rainfall — Incorrect. Dry regions with uncertain rainfall cannot support intensive cultivation, so they need less labour. Kumar ties the most unequal structures to high productivity and a large demand for labour, which dry regions lack.

Option (3) Regions settled under the raiyatwari system — Incorrect. Raiyatwari was a colonial land revenue system in which cultivators paid revenue directly to the state. Kumar explains inequality by how much labour the land needed, and a revenue system does not decide that.

Option (4) Regions of assured irrigation needing intensive cultivation — Correct. Kumar finds a direct link between agricultural productivity and agrarian structure. Where irrigation was assured, intensive cultivation needed much more labour, and here the most unequal agrarian structures developed.
