Answer:
A caste system is the correct answer.
Step-by-step explanation:
A caste system is defined as a class structure that is determined by birth, meaning that you will be what your parents are: if they are rich, you will be too, but if they are poor, you will also be poor. The caste system is not recognized by Muslim people, but it was adopted after the cultural exchange in the regions of Pakistan, India, and Persia.
