Question

The one who answers first I will mark you as brainleist......​

Answer 1

hey sister,

your answer is F.

F is grandmother of D.

As,

D is son of B and B is brother of C. This means their parents are same and A is father of C so he is also father of B but A is not their father this means he is their step father. As F is spouse of A this means she is mother of B and C. therefore F is grandmother of D.

hope this helps you.

mark me as brainliest....
