Heya Dear,

Answer - A#B$C'D

Solution - A#B implies: A is MOTHER of B so A is disqualified as father is supposed to be a male.

B$C implies: B is BROTHER of C so B is a male and is kept aside.

C*D implies: C is DAUGHTER of D so C is disqualified.

Now we’re left with B and D, but B is brother of C and C is daughter of D( as stated above ) so that means that B is son of D.

Which in turn implies that D is the father.

Also, A is the mother and A and D have two children namely B and C.

Hope it helps
