So, options A and D are incorrect. 2. **T is a man married to one of the group members:** T is married. Since P and S are unmarried, T must be married to either Q or R. 3. **Q is the brother of P:** This confirms Q is male. 4. **Who is the spouse of R?** We know R's spouse must be either T or Q. * **Consider if R's spouse is Q:** If R is married to Q, then Q (male) is married to R. This would leave T (a man who *must* be married to one of the group members) with no one to marry, as P and S are unmarried and R is married to Q. This contradicts the statement that T is married to one of the group members. * **Therefore, R's spouse cannot be Q.** 5. **By elimination:** Since P and S are unmarried, and R cannot be married to Q (as it leaves T without a spouse), the only remaining person for R to be married to is T. The final answer is B) T.
