(II). One couple has parents and their children in the family.
(III). A is the son of C and E is the daughter of A.
(IV). D is the daughter of F who is the mother of E. What relationship do D and E bear to each other ?

A. Sister and Brother

B. Mother and Son

C. Grandmother and Grand daughter

D. Sister

E. None of these

Answer: D. Sister

E is the daughter of A and F is the mother of E. So, A is the father of E and hence the husband of F. Now, D is the daughter of F. So, D and E are the daughters of A and F.
Also, A is the son of C. Now, only B remains. Thus, B and C are the parents of A.

Clearly, D and E are sisters.
