The correct answer is - C) to provide social control and conformity according to one's birth.
The caste system, which was a long lasting cultural trait in India, was a system that was designed for specialization of the people, but also for permitting people from one caste to move into another and thus disrupting the system. In the caste system, people were destined from their birth in which caste will they be, and that was for life, without the option of moving upwards into another higher caste.
Nowadays, the caste system is not legal in India, but still there a cases, mainly in the rural areas, where people are practicing it as it was traditionally.
