If A + B means A is the mother of B;A – B meansA is the brother B;A % ...
Given Relationships:
- A B means A is the mother of B
- A – B means A is the brother of B
- A % B means A is the father of B
- A x B means A is the sister of B

We need to determine the relationship between P and Q, which indicates that P is the maternal uncle of Q.

Solution:
Maternal uncle means the brother of one's mother. So, we need to find a relationship that connects P to Q through Q's mother.

Let's analyze the given options one by one:

a) Q – N M x P: This implies that Q is the sister of N, who is the mother of M, and P is the sister of M. This does not give any information about the relationship between P and Q's mother, so this option can be eliminated.

b) P S x N – Q:
This implies that P is the brother of S, who is the sister of N, and Q is the sister of N. This does not give any information about the relationship between P and Q's mother, so this option can be eliminated.

c) P – M N x Q: This implies that P is the brother of M, who is the father of Q, and Q is the sister of N. This indicates that P is the maternal uncle of Q, as M is the father of Q and P is his brother (i.e., Q's mother's brother). Hence, this option is the correct answer.

d) Q – S % P: This implies that Q is the sister of S, who is the father of P. This does not give any information about the relationship between P and Q's mother, so this option can be eliminated.

Therefore, the correct answer is option (c) P – M N x Q.
