P and Q are M's parents. M and N are siblings. Q is N's mother. What is P to M?
Correct answer: B. Father
- A. Mother
- B. Father
- C. Sister
- D. Brother
Explanation
P and Q are the two parents, and Q is identified as the mother, so P must be the father. M and N being siblings simply confirms that both children share the same pair of parents. Sister and brother describe the wrong generation entirely, since P is a parent.
