Which of the following was the basic unit of Vedic Society?

Correct answer: Parivar

Explanation: The correct answer is C. Parivar. In early Vedic society, the family or 'Parivar' formed the basic unit of social organization. The Kula (family) was headed by the Grihapati (householder), who played an important role in religious and economic activities. The Parivar consisted of the father, mother, children, and other close relatives living together in a household. Over time, multiple families formed Gramas (villages), and these eventually formed larger units like Jana (tribe), but the starting and core social unit remained the family.
