The correct answer is A. Fixed and hierarchical.
Explanation
The Indian caste system is among the oldest forms of social stratification that has survived throughout the years. This system that divides Hindus into rigid hierarchical groups based on their work and duty is over 3000 years old.
This caste system was divided into four different levels: Brahmins, Kshatriyas, Vaishyas, and Shudras. The Brahmins are located at the top of this hierarchy system above the other castes, this caste was made up of teachers and intellectuals. The second caste in hierarchical order was the Kshatriyas, which was made up of warriors and rulers. The third caste in hierarchical order was the Vaishyas, a group made up of merchants. Finally, the fourth caste was Shudras, which was made up of the individuals who did all the menial work. From the above, it can be concluded that the castes of Indian society were fixed and hierarchical so the correct answer is A.
