Statements:
1. R's sister J has married Ts brother L, who is the only son of his parents.

Answer: D
From 1, we know that L is T's brother and J's husband. Since L is the only son of his parents, T is L's sister.
From 2, we know that K is L's daughter.
Thus, from 1 and 2, we conclude that T is the sister of K's father i.e. T is K's aunt.
