Answer:
C. A lack of social mobility.
Explanation:
The caste system in India is a system of demarcation, alienation, or classification of society into groups based on their professions and class or belonging. This systematized level not only gave certain groups an advantage over the lower ones, but it also led to great stigmatization further leading to even alienation and discrimination.
The four levels or groups of the caste system were the Brahmins, Kshatriyas, Vaishyas, and lastly the Shudras. While the upper ones enjoy all amenities of life and lead a free life, the lower ones, especially the Shudras were more of the outcaste. They were made to do all of the odd jobs, the dirty work that was deemed improper. And added to that, they were again looked down upon by the ones in the higher class, which resulted in their discrimination intentionally and unintentionally, but mostly intentionally.
This classification of the people or society into such groups was a direct result of the social immobility, the lack of an influx or interaction among the different people, and their insistence on maintaining their own 'circles', thereby obstructing the need or chance to 'mingle' with each other outside of their respective 'circles'.
