Can someone give me an explanation of the ways the groups within the Indian caste system interact or relate to one another

The answer is below

Explanation:

There are four groups within the Indian caste system and they are Brahmins, Kshatriyas, Vaishyas, and the Shudras.

Each of the groups is defined by its hierarchical wealth status. People in each of these groups only communicate within themselves.

That is, the people in the upper class only interact with those in the upper class, but not with those in the middle class or lower class, the same thing applies to other classes.

The India Caste system interaction is based on the belief that interacting with those in the class below you is humiliating and embarrassing.
