How are N and D related ?
I. A is the sister of D.
II. D is the mother of R who is the only son of N.
Clearly, statement I alone is insufficient as N is not mentioned in the first statement.
In the second statement, it is given that D is the mother of R and R is the only son of N.
=> N is the father of R.
Thus, N is the husband of D.
$$\therefore$$ Statement II alone is sufficient.
=> Ans - (B)
