Answer :

D. Matrilineal descent
This means that one's kinship is only tracked through the mother.

The correct answer is D.

Matrilineality is a system in which the descent is made through the mother and the maternal ancestors.

The matrilineal descent is a line of descent from a female ancestor to a descendant in which individuals of all intermediate generations are mothers. In a system of matrilineal descent, it is contemplated that an individual corresponds to the same group of descendants as his/her mother.
