Step-by-step explanation:
The subject of this question is Social Studies.
The caste system is a social phenomenon that is studied in the field of Social Studies. It is a closed stratification system where people are born into a particular social group, or caste, and remain in it for their entire lives. The caste system determines various aspects of an individual's life, including their occupation, marriage partners, and housing. It restricts social mobility, meaning that individuals have limited opportunities to improve their social position.
For example, in India's caste system, people are assigned occupations based on their caste, regardless of their individual talents or potential. They are also expected to marry within their caste. This lack of social mobility limits a person's ability to change their social standing within their lifetime.
