Read the given information carefully and answer the questions based on it: In a family, D is mother-in-law of N. N's spouse is only paternal aunt of E. P is the mother of E's sibling. V is the grandchild of P's father-in-law. C is father-in-law of V's mother who is U. G is the only brother of N's spouse, and L is G's father. A is G's son, so A is the only nephew of N's spouse. R is parent of L's only son-in-law and parent of H. Gender of G and H is same but different to N's child.

If R has a daughter, then, how will N's spouse relate to R's daughter?

Correct answer: A

In a blood-relations puzzle, an indirect relationship is worked out by first fixing every stated parent-child and sibling link from the clues -- especially the ones marked 'only', which are the actual keys that pin a relation to one specific person -- then reading off the standard in-law term: a person's brother's wife is that person's sister-in-law, and equally, a person's husband's sister is that person's sister-in-law.

  1. 'D is mother-in-law of N' fixes D as the mother of N's spouse.

  2. 'N's spouse is only paternal aunt of E' means E's father is a sibling of N's spouse. Since E's father is necessarily male, and 'G is the only brother of N's spouse' tells us N's spouse has exactly one male sibling, E's father must be that one brother: E's father is G.

  3. 'L is G's father' therefore also makes L the paternal grandfather of E (through G).

  4. The clue 'R is parent of L's only son-in-law' presupposes L has exactly one married daughter -- a son-in-law is, by definition, the husband of a daughter. Call that daughter Q.

  5. Q shares father L with G, so Q is G's sister, and therefore a paternal aunt of E. Since N's spouse is E's ONLY paternal aunt, Q must be N's spouse.

  6. So N's spouse is L's daughter, N (her husband) is L's only son-in-law, and 'R is parent of L's only son-in-law' fixes R as N's parent.

  7. 'A is G's son' makes A the child of N's spouse's brother, i.e. her nephew -- consistent with 'A is the only nephew of N's spouse.'

  8. If R has a daughter, that daughter is N's sibling, and N's spouse, married to that sibling's brother, is the daughter's sister-in-law.

Checking against the other options by value: 'Sister' would need R's daughter and N's spouse to share a parent, but N's spouse's parents are L and D, not R; 'Cousin' would need a relation through a shared grandparent's other child, which is not established here; 'Uncle' and 'Brother-in-law' are male terms, but N's spouse is female (confirmed by her being called E's paternal aunt), so they are ruled out on gender alone. Sister-in-law, the wife of R's daughter's brother, is the only relation consistent with every clue.
