? C has three children but we can't say that he has three daughters or three sons.
So, options (a) and (b) are incorrect.
Also, we don't know that B is a boy or girl.
So, option (c) is also incorrect.
Father's wife ? Mother; Mother's daughter ? Sister; Sister's younger brother ? His brother.
So, the boy is Deepak's brother.
None of these
S is Great grandmother of N
T is Grand father
None of these
NA
As 'S' is a female in options (a) and (b), they can be rejected directly. The gender of 'S' in option (c) is not known, hence, it can also be eliminated. Now, check option (d).
(c) is ruled out because we need two generation-change signs (? and ÷) between P and T. Same is the case with (a). Again, (d) is ruled out because P + Q does not give the sex of P. Now, check (b)
(P) (-) ? Q (+)

R(-)
