The correct answer is: Cousin.
P’s father is Q’s son. This means that P is Q’s grandson. M is the paternal uncle of P. This means that M is the brother of P’s father, who is Q. N is the brother of Q. This means that N is the uncle of P. Therefore, N is the cousin of P.
Here is a diagram to illustrate the relationships:
- Q *
- / \
- P N
P is the grandson of Q. M is the brother of Q, and therefore the uncle of P. N is the brother of Q, and therefore the uncle of P. Therefore, N is the cousin of P.
The other options are incorrect because:
- A. Brother: N is the brother of Q, not the brother of M.
- B. Cousin: N is the cousin of P, not the cousin of M.
- D. Data inadequate: There is enough data to answer the question.
- E. None of these: N is related to M as a cousin.
