The question requires us to determine which person among A, B, C, and D plays only tennis, given the other sports each one plays. Here's how we can solve it step-by-step:
Identifying the players and their sports:
A: No specific information is given, so A could potentially play only tennis.
B: Plays both tennis and football.
C: Plays both tennis and football.
D: Plays tennis and badminton, but not chess.
Analyzing possibilities:
A: Since there's no mention of A playing any other sport besides tennis, A could be the person who plays only tennis.
B: Since B plays football as well, B is not the correct option for playing only tennis.
C: Since C plays football as well, C is not the correct option for playing only tennis.
D: Since D plays badminton, D is not the correct option for playing only tennis.
Conclusion: Based on the analysis, A is the only person who plays only tennis.
