Which action is illegal and can result in warnings or deductions?

• A. Headbutting the opponent.
• B. Punching when the opponent is down.
• C. Punching after the referee has issued a verbal warning for a previous foul.
• D. Clinching without attempting to break.

Answer: (B)

Punching when the opponent is down is illegal because a fighter who has been knocked to the canvas cannot defend themselves, and continuing to strike a downed opponent endangers them. This rule exists to protect boxers and maintain fair play; a referee can warn the offender, deduct points, or even disqualify them for this kind of foul, depending on the severity and circumstances. While other fouls like headbutting are also violations that can bring warnings or deductions, the direct act of punching a downed opponent is the clearest, most common cause for penalties in these situations.
