A is father of C and D is son of B. E is brother of A, If C is sister of D, How is B related to E ?

Daughter
E is brother of A, If C is sister of D, How is B related to E ? A. Daughter B. Brother-in-law
Husband
Sister-in-law

The correct answer is: B. Brother-in-law.

A is the father of C, and C is the sister of D. This means that A and B are married, and C and D are siblings. E is the brother of A. This means that E is also the brother-in-law of B.

The other options are incorrect because:

  • A daughter is a female child. B is not a female child.
  • A husband is a man who is married to a woman. B is not a man.
  • A sister-in-law is the wife of a brother or the sister of a husband. B is not the wife of a brother or the sister of a husband.
