Detailed Solution & Explanation
Let us systematically analyze the given relationships to deduce the required connection.
1. **Analyze the first statement:** "P and Q are brothers."
This establishes that P and Q are male individuals and share the same parents. They belong to the same generation.
2. **Analyze the second statement:** "R and S are sisters."
This establishes that R and S are female individuals and share the same parents. They belong to the same generation.
3. **Analyze the third statement:** "P's son is R's brother."
Let's denote P's son as X. So, X is a male individual.
The statement implies that X is the brother of R.
Since R and S are sisters (from statement 2), X, R, and S are all siblings.
As X is P's son, P is the father of X.
Since X, R, and S are siblings, P must also be the father of R and S.
Therefore, P is the father of R and S.
4. **Combine the deductions to establish the relationship between Q and R (or S):**
From step 1, P and Q are brothers.
From step 3, P is the father of R and S.
Since Q is P's brother, Q is the paternal uncle of P's children, which include R and S.
Thus, Q is the uncle of R and Q is the uncle of S.
5. **Address the discrepancy in the question:** The question asks, "How is Q related to K?". However, the individual "K" is not mentioned anywhere in the problem statement. This appears to be a typographical error. Given the options and the derived relationships, it is highly probable that the question intended to ask "How is Q related to R?" or "How is Q related to S?".
Assuming the question meant to ask "How is Q related to R?" (or S, as the relationship would be identical), then based on our derivation in step 4, Q is R's uncle.
6. **Conclusion:**
Based on the logical deduction, Q is the paternal uncle of R (and S). If we assume the question intended to ask about R (or S) instead of the unmentioned K, then Q's relationship is that of an uncle.
Therefore, the correct choice is **Option A**.
