If P $ Q means P is the father of Q; P # Q means P is the mother of Q and P * Q means P is the sister of Q, then N # L $ P * Q shows which of the relation of Q to N?

The correct answer is D. Data is inadequate.

We know that P $ Q means P is the father of Q, P # Q means P is the mother of Q, and P * Q means P is the sister of Q. We are given that N # L $ P * Q. This means that N is the mother of L, and L is the sister of P. However, we do not know the relationship between N and P. It is possible that N is the mother of P, in which case Q would be N’s son or daughter. It is also possible that N is the sister of P, in which case Q would be N’s nephew or niece. Without knowing the relationship between N and P, we cannot determine the relationship between Q and N.
