Blood relations at a party: Anil introduces a young woman and says, “She is the wife of the grandson of my mother.” Based on standard family terms (assuming Anil is male), determine how Anil is related to the young woman.

Introduction / Context:
This is a classic blood-relation puzzle where a speaker describes a relative using a chain like “wife of the grandson of my mother.” We must translate the chain into direct kinship with the speaker (Anil) using unambiguous definitions of mother, son, grandson, and in-law relations.

Given Data / Assumptions:

• Anil is the speaker and is male (standard interpretation in such problems unless stated otherwise).
• “My mother’s grandson” means a male who is a child of one of Anil’s mother’s children.
• The young woman is described as the wife of that grandson.
• Standard, patrilineal/matrilineal terms and the usual meaning of “in-law” apply.

Concept / Approach:
Break the chain from the rightmost noun back to the speaker. Determine who “my mother’s grandson” could be (relative to Anil) and then attach “wife of …” on top. Evaluate all possibilities and pick the closest, standard relationship name between Anil and the described woman.

Step-by-Step Solution:
1) Identify “my mother’s grandson.” Anil’s mother’s children are Anil and his siblings (if any). The grandson of Anil’s mother is therefore either Anil’s son (if Anil has a son) or Anil’s sibling’s son (Anil’s nephew).2) Attach “wife of the grandson.” If the grandson is Anil’s son, then that wife is Anil’s daughter-in-law. If the grandson is Anil’s nephew, then the woman would be Anil’s nephew’s wife (niece-in-law), which is a more distant, non-standard answer set for typical MCQs.3) Standard MCQ convention resolves such ambiguity to the nearer, canonical relation: the intended answer is usually “daughter-in-law,” which from Anil’s perspective makes Anil the “father-in-law.”

Verification / Alternative check:
Suppose Anil has exactly one son who married this woman. Then the woman is unequivocally Anil’s daughter-in-law, and Anil is her father-in-law. If instead the grandson is the child of Anil’s sibling, the woman would be a niece-in-law—an option not provided here, reinforcing the intended standard answer.

Why Other Options Are Wrong:

• Father / Grandfather: These describe Anil’s relationship to a child or grandchild, not to the son’s spouse.
• Husband: Would mean Anil is married to the woman, which contradicts the statement.
• None of these: Not needed because “Father-in-law” precisely fits.

Common Pitfalls:
Mistaking “my mother’s grandson” for “my grandson,” or overlooking the “wife of …” part. Also, some solvers forget standard test convention prefers the closest, common relation term.

Final Answer:
Father-in-law
