the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question,
the data either in statement I alone or in statement II alone are sufficient to answer the question,
the data in both statements I and II together are necessary to answer the question.

Solution :From I, 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 II, we know that K is L.s daughter. Thus, from I and II, we CONCLUDE that T is the sister of K.s father i.e. Tis K.s aunt.
