Show answer & explanation
Correct answer: D
Concept
In blood-relation problems, convert each statement into a directed family link and join only links that share a person. Gender words identify the exact relation, while marriage links create in-law relations between the two families.
Application
L is the mother of E, and E is the sister of M. Therefore E and M are siblings, so L is also the mother of M.
N is the husband of M. Thus M is L’s daughter and N is L’s son-in-law.
O is the father of N. Therefore O is the father of L’s son-in-law.
Cross-check and contrast
Tracing from L gives: daughter M → M’s husband N → N’s father O. Hence O is L’s daughter’s husband’s father.
Daughter’s husband identifies N, the son-in-law.
Daughter’s father refers to M’s male parent, whose identity is not given.
Daughter’s husband’s brother would require a brother of N, but no such person is stated.
Daughter’s husband’s father identifies O through the chain M → N → O.
Therefore, O is L’s daughter’s husband’s father.
