The correct option is A Kerala
Matriarchy is a social organization where the mother is the head of the family. In Kerala, women enjoy a higher status as compared to other Indian states. This is reflected by Kerala's sex ratio and literacy rates. Marumakkathayam was a matrilineal inheritance system prevalent in Kerala, where property inheritance was traced through females. Officially, the state has banned matrilineal family structure by the Kerala Joint Hindu Family System (Abolition) Act, 1975. Kerala state legislature passed this act. Hence, option B Kerala is the correct answer.
