Final answer:
An (3) intercaste marriage is the appropriate term for a union between individuals from different social classes that may involve the transference of power.
Step-by-step explanation:
A marriage between two people from different social classes involving the transference of power is typically called an intercaste marriage. Intercaste marriage is a form of exogamous marriage, which is the union of spouses from different social categories, often based on values such as love and compatibility.
Societies have various forms of marriage, including endogamous marriages (within the same social class), arranged marriages, interfaith marriages, marriages of convenience, and others such as monogamy, polygamy, polygyny, and polyandry. These types of marriages are designed to meet social, cultural, and sometimes political or economic goals, emphasizing that marriage is a culturally defined institution that varies widely across different societies.
