Show answer & explanation
Correct answer: A
To determine which option shows that "P is the maternal uncle of Q," we first need to break down the symbols provided:
1: Mother (A 1 B = A is the mother of B)
2: Brother (A 2 B = A is the brother of B)
3: Father (A 3 B = A is the father of B)
4: Sister (A 4 B = A is the sister of B)
To be a maternal uncle, P must be the brother of Q's mother. Therefore, the chain must show that P is a brother to someone who is the mother of Q.
Step-by-Step Analysis of the Required Chain
P is the brother of M: P 2 M
M is the mother of Q: M 1 Q
Combined chain: P 2 M 1 Q
Looking at the options, we need to find a variation of this logic that confirms the relationship.
