    D) E and F are children of D. 

    E) None of these 

    Correct Answer: B

    Solution :

    Explanation Option [b] is correct. Clearly, there are three males and three females. Now, A, E and B are sons and hence males. So, C, D and F are females. D has one male and one female child. Clearly, A and D form a couple having two children, namely B and C. Hence, A is the husband of D. Rest of the options is incorrect because of the correctness of option [b].
