B.
II alone is sufficient while I alone is not sufficient
C.
Either I or II is sufficient
D.
Neither I nor II is sufficient
Answer
E.
Both I and II are sufficient

Answer: Option D

Solution

Answer: Option D
Solution:
From II, we know that N is K's son and K is B's grandfather. Thus, N is the son of B's grandfather i.e. N is either father or uncle of B.
From I, B is the daughter of M. So, M is either father or mother of B.
Clearly, the correct relationship between M and N cannot be deduced.
