Concept:Blood relation questions are solved by drawing a clear family tree from the given statements.Explanation:From statement I: $N$ is the son of $P$, and $P$ is the wife of $Q$.So, $P$ is the mother of $N$, and $Q$ is the father of $N$.Since $R$ is the father-in-law of $Q$, and $Q$'s wife is $P$, $R$ must be the father of $P$.$M$ is the son of $R$, so $M$ is the brother of $P$.Thus, $M$ is the brother of $N$'s mother, which means $M$ is the maternal uncle of $N$.Therefore, statement I alone is sufficient to answer the question.From statement II: $Q$ is the brother of $M$, and both are sons of $R$.$R$ is the father-in-law of $P$, who is the mother of $N$.This only tells that $P$'s husband is one of $R$'s sons, but it is not clear whether that son is $Q$ or $M$.Hence, the exact relationship between $M$ and $N$ cannot be determined from statement II alone.Answer:Option A — Statement I alone is sufficient to answer the question.
