Blood relations (compound statement parsing): Identify how the lady’s husband is related to Anupam. Spoken by Anupam to a lady in a car: “The only daughter of the brother of my wife is the sister-in-law of the brother of your sister.” Use standard Indian-kinship interpretation of “sister-in-law” (brother’s wife or wife’s sister) and determine the relation asked. Choose the correct relationship.

Given data (rewrite with labels)

• My wife's brother = Anupam's brother-in-law. His only daughter = X.
• Lady's side: “the brother of your sister” = the lady's brother (LB).
• Statement: X is the sister-in-law of LB. For a man, “sister-in-law” means either (i) brother's wife, or (ii) wife's sister.

Concept/Approach
Test which interpretation makes the family graph consistent and also fixes the target relation “lady’s husband” ↔ Anupam.

Step-by-step deduction
• If X were LB's brother's wife, then X would be the wife of the lady's husband—contradiction (a man cannot have two wives here). So reject (i). • Therefore, X must be the wife’s sister of LB ⇒ LB is married to Y, where Y is X's sister. • X and Y are daughters of Anupam's wife's brother (maternal uncle's daughters). A common, consistent resolution is that the lady is Anupam's daughter; her brother (LB) married his maternal cousin Y (X's sister). Hence the lady’s husband is Anupam’s son-in-law.

Quick verification
If the lady is Anupam’s daughter, then “the brother of your sister” refers to Anupam’s son (LB). X (maternal-uncle’s daughter) being the sister-in-law of LB is satisfied when LB marries Y (X’s sister). Asked relation then matches: lady’s husband = Anupam’s son-in-law.

Common pitfalls
Confusing “brother of your sister” with the lady's husband; it refers to the lady's brother, not spouse.
