Detailed Solution & Explanation

Let us analyze the family relations step-by-step:
1. **Identify the brothers and their spouses**:
- "Q and R are brothers." Both Q\displaystyle Q and R\displaystyle R are males.
- "W is married to R." Since R\displaystyle R is male, W\displaystyle W is female, and they form one married couple (R,W)\displaystyle (R, W).
- "E is a doctor married to one of the brothers." Since R\displaystyle R is married to W\displaystyle W, E\displaystyle E must be married to Q\displaystyle Q. They form the second married couple (Q,E)\displaystyle (Q, E), where E\displaystyle E is female.

2. **Identify the children**:
- The family has "two children" in total, one of whom is T\displaystyle T (a boy).
- "Y is their [R and W's] only child." This means Y\displaystyle Y is the child of R\displaystyle R and W\displaystyle W. Since Y\displaystyle Y is the *only* child of R\displaystyle R and W\displaystyle W, the other child T\displaystyle T must belong to the other couple, Q\displaystyle Q and E\displaystyle E.

3. **Determine the relation of T to Q**:
Since T\displaystyle T is the child of Q\displaystyle Q and E\displaystyle E, and T\displaystyle T is a boy, T\displaystyle T is the son of Q\displaystyle Q (and E\displaystyle E).

Hence, **Option D** is the correct answer.
