Question

B is the daughter of A. C is the husband of B. D is the son of C. How is A related to D?

1. A. Father
2. B. Grandfather
3. C. Grandmother
4. D. Cannot be determined (Correct answer)

Correct Answer

Option D — Cannot be determined

Detailed Solution & Explanation

The correct answer is Cannot be determined.

Key Points

• Trace the chain: B is A's daughter, C is B's husband, and D is C's son — so D is the child of B and C, making D A's grandchild.
• A is therefore D's grandparent, but the question asks specifically how A is related, and the options separate Grandfather from Grandmother.
• Nothing in the statements reveals A's gender: A is identified only as B's parent, which A could be as either father or mother.
• Since the relation cannot be narrowed to one of the two named options, the answer is cannot be determined.

Additional Information

• Gender-indeterminate names are a deliberate device. Relationships such as *parent, child, sibling, spouse* and *cousin* carry no gender, whereas *father, mother, son, daughter, brother, sister, husband* and *wife* do.
• Whenever "Cannot be determined" appears among the options, check explicitly whether every required attribute — usually gender or a unique identification — has actually been supplied.
• Here the generation is fully determined (grandparent) even though the gender is not, which is exactly the gap the question is testing.
