Which of the following is a correct explanation of Agrarian Structure?

The correct answer is Option (1) → Agrarian structure refers to the structure and distribution of landholding

Option (1) Agrarian structure refers to the structure and distribution of landholding — Correct. Agricultural land is the most important productive resource in rural areas, and it is not equally distributed. The term agrarian structure is often used to refer to the structure or distribution of landholding.

Option (2) Agrarian structure is a system of caste structure — Incorrect. Caste and land are closely linked: in most regions the major landowning groups belong to the upper castes, and each region has one or two major landowning castes. But the agrarian structure is the pattern of landholding; caste is a separate institution connected with it.

Option (3) Agrarian structure is a system of class — Incorrect. Because land is the main productive resource, access to land shapes the rural class structure. Class follows from the agrarian structure; it is not the agrarian structure itself.
