    Solution

    From statement I alone, L is only sister of H. H is married to I. G is only daughter of J. K is only son of H. I is father of F. We get: Case 1: When J is married to K. Case 2: When J is married to F. F is either mother or paternal aunt of G. So, data given in statement I alone is not sufficient to answer the question. From statement II alone, K is only brother of F. F is only daughter of I. J is brother-in-law of K. H is sister of L. I is brother-in-law of L. Gender of G and L are same. We get: F is mother of G. So, data given in statement II alone is sufficient to answer the question. Therefore, data given in statement II alone is sufficient to answer the question while the data given in statement I alone is not sufficient to answer the question.
