What do you understand by the term “Endogamy”?

The correct answer is Option (2) → Refers to marriage within a unit

Each option is a type of marriage, and each has its own name.

Option (1) The practice of a man having several wives — Incorrect. This is polygyny.

Option (2) Refers to marriage within a unit — Correct. Endogamy is marriage within a unit. The unit could be a kin group, a caste, or a group living in the same locality.

Option (3) Refers to marriage outside the unit — Incorrect. This is exogamy (literally, marrying outside). Families that claimed high status married their daughters into families outside the kin, and kanyadana, the gift of a daughter in marriage, came to be seen as an important religious duty of the father.

Option (4) The practice of a woman having several husbands — Incorrect. This is polyandry.
