Options

A. Brother
B. Sister
C. Brother-in-law
D. Sister-in-law

Explanation

To solve the problem, we need to analyze the relationships step by step:

1. **Identify Relationships**:
- A is the father of C and D.
- D is the son of B.
- E is the brother of A.
- C is the sister of D.

2. **Determine the Gender of Each Person**:
- Since A is the father, A is male (A+).
- C and D are children of A. Since C is a sister of D, C is female (C-) and D is male (D+).
- D is the son of B, which means B must be the mother of D (B-).
- E is the brother of A, so E is also male (E+).

3. **Establish the Relationship Between B and E**:
- Since A is the father of C and D, and B is the mother of D, B must also be the mother of C.
- Therefore, B is the wife of A.
- Since E is the brother of A, B (the wife of A) is E's sister-in-law.

4. **Conclusion**:
- Thus, B is related to E as his sister-in-law.

**Final Answer**: B is E's sister-in-law.
