**Explanation : **

## 5 members A, B, C, D, E in a family

A and B are a married couple, so they are husband and wife.

D is the father of C, so C is the child of D.

E is D’s son, so E is the brother of C.

A and C are sisters, so they have the same parents.

Finally, I would use the family tree and the definitions to find the relation of E to B. For example:

E is the brother of C, who is the spouse of B, so E is the brother-in-law of B.

Therefore, the correct answer is © All four statements together are sufficient to answer the Question.
