Answer:
When a person is assigned a status at birth and must remain in it throughout his or her life, it is a caste system.
Explanation:
A caste system is applied in some societies and consists of the assignment of an individual to a social stratum by birthright, being forced to remain in that status and even relate to people of the same social category and allow endogamy.
It is a system that exists in ancient societies, an example being the Hindu caste system or South African apartheid. Other cultures that made use of the caste system were the Arab and Hebrew.
Unlike the caste system, the class system consists of inclusion in a specific social class, without the intervention of the birthright.
