Explanation:

- Caste endogamy: In North India, people are expected to marry within their caste but follow exogamy regarding village (not marrying within the same village).

- Local fictive kinship: People in the same village often see themselves as related through symbolic or “fictive” kinship, making marriage within the village taboo.

- Territorial stabilization of kin groups: Over generations, kin groups stabilize in certain villages, reinforcing avoidance of local marriage.

- Gotra: Ancestral clan rules (gotra exogamy) prevent marriage within the same gotra, often linked to avoiding marriage with “kin.”

Let’s check the options:

- Option 1 (1 and 3 only): Excludes fictive kinship and gotra, both highly relevant.

- Option 2 (1, 2 and 4 only): Misses territorial stabilization, which is crucial.

- Option 3 (2 and 4 only): Lacks both caste endogamy and territorial stabilization.

- Option 4 (1, 2, 3, and 4): Covers all four interrelated factors.

Correct Answer:

Option 4 (1, 2, 3, and 4)
