What term describes the legally mandated marriage within the same caste?

Explanation

The correct answer is B. Endogeny refers to the practice of legally enforced marriage within a caste. Endogamy (option A) is the more commonly used term for marrying within a social group but is not specifically about legal enforcement. Exegesis (option C) relates to critical explanation or interpretation, usually of texts. Exclusion (option D) refers to the act of keeping out or denying access. Exogamy (option E) means marrying outside one's group.
