Pointing to a girl, Abhishek says: “She is the daughter of the only child of my father.” How is Abhishek’s wife related to that girl?

Introduction / Context:
This relation chain reduces to a parent-child pair when we resolve “only child of my father.” We then ask for the kinship of Abhishek’s wife to the identified girl.

Given Data / Assumptions:

• “Only child of my father” = Abhishek himself (he has no siblings).
• The girl is the daughter of Abhishek.
• Abhishek is married (has a wife).

Concept / Approach:
If the girl is Abhishek’s daughter, then Abhishek’s wife is the girl’s mother (biological or social mother in standard MCQ interpretation).

Step-by-Step Solution:
Replace “only child of my father” with Abhishek → “She is the daughter of Abhishek.”Therefore Abhishek’s wife is the mother of the girl.

Verification / Alternative check:
Any alternate reading (e.g., adoption complexities) is outside scope; MCQs use straightforward definitions.

Why Other Options Are Wrong:
They represent other family roles (aunt, sister, daughter) that do not fit a child’s relation to her parents.

Common Pitfalls:
Misreading “only child” as “only grandchild” or swapping generations.

Final Answer:
Mother
