• C. Father
• D. Cannot be established (cannot be determined)
• E.

Hint:

When solving family relation questions, ensure that you analyze all available relationships and the specific phrasing in the question carefully before drawing conclusions.

Answer 1

The Correct Option is D

From the given information, we know the relationships between various family members. However, the exact relationship of E to F is not explicitly mentioned. Since E is the unmarried engineer, and F is the accountant, their precise relationship cannot be definitively concluded from the available information. Thus, the correct answer is (d) Cannot be established. 

Answer 2

Build the family tree step by step from the clues instead of guessing at the final relationship.

1. Option A (Brother): This would require E to definitely be male, but E is only ever called the "unmarried engineer" — the gender is never stated, so this cannot be confirmed.
2. Option B (Sister): This would require E to definitely be female, which is equally unconfirmed by the given information.
3. Option C (Father): F is explicitly the son of B, and E is a sibling of F, both children of the same parents, so E cannot be F's father.
4. Option D (Cannot be established): Tracing the clues: C, the lawyer, is called the daughter-in-law of A, so C's husband is A's son; the doctor is married to C, so the doctor is A's son. F, the accountant, is the son of B and the brother of E, and A is the grandmother of F, which places B as A's son and the parent of E and F. Since D is married to "the lady teacher" and no other lady teacher fits the tree, A takes the teacher role, married to D, while B takes the doctor role, married to C. This confirms B and C are E and F's parents, making E a sibling of F — but since E's gender is never stated anywhere in the clues, whether E is F's brother or sister cannot be pinned down.

Since E is confirmed to be F's sibling, but E's gender is never given, the exact relationship cannot be established from the information provided.

Hence, the correct answer is Cannot be established (cannot be determined).
