C Correct answer
Explanation

Condition A says best and worst are the same age (twins). Condition B says the best singer's twin and the worst singer are opposite sex. If D and A are twins (son/daughter), and D is best, her twin A is male. If the worst is S (female), they are opposite sex. This fits the logic puzzles common in IQ tests.
