Option A: Incorrect because the passage does not state that bad athletes can't want to win; it only links athletes' desire to win with eating a well-balanced diet.

Option B: Correct because the passage implies athletes who do not eat a well-balanced diet are bad athletes, based on the logic of winning and proper nutrition.

Option C: Incorrect because the passage does not imply all athletes eating a balanced diet are good; it only links a desire to win with a balanced diet.

Option D: Incorrect because the passage doesn’t claim all athletes who want to win are good, just that they eat a well-balanced diet, which doesn’t define athletic quality.
