The correct answer is (c) Jaintias.
The Jaintias are a matrilineal society, which means that property and inheritance are passed down through the female line. The eldest daughter is the head of the household and inherits all of her father’s property. The sons live with their wives and children in their mother’s household.
The Garos and Khasis are also matrilineal societies, but the Rabhas are a patrilineal society. In a patrilineal society, property and inheritance are passed down through the male line. The eldest son is the head of the household and inherits all of his father’s property. The daughters live with their husbands and children in their father’s household.
Matrilineal societies are relatively rare in the world, but they are found in many parts of Asia, Africa, and Oceania. They are often associated with cultures that have a strong emphasis on the role of women.
