Correct Answer & Explanation
Option A
Let's establish the family connections:
• A is the sister of B.
• C is the father of A. (Since A is B's sister, C is also the father of B).
• B is the son of D. (Since C is the father of B and D is the mother of B, C and D are a married couple).
• D is the mother of E. (Since D is the mother of B and E, B and E are siblings. C is the father of B, so C must also be the father of E).
• Therefore, C is the father of E.
