Dominant Caste

The correct answer is Option (2) - Dominant Caste.

In each region, there are usually just one or two major landowning castes, who are also numerically very important. Such groups were termed by the sociologist M.N. Srinivas as dominant castes. In each region, the dominant caste is the most powerful group, economically and politically, and dominates local society. Examples of dominant landowning groups are the Jats and Rajputs of U.P., the Vokkaligas and Lingayats in Karnataka, Kammas and Reddis in Andhra Pradesh, and Jat Sikhs in Punjab.
