• A. A knockdown happens only when a boxer is knocked out of the ring.
• B. A knockdown occurs when a boxer is knocked to the canvas and cannot immediately rise and continue, prompting a referee count.
• C. A knockdown is declared if the boxer is warned for holding and clinching.
• D. A knockdown is when the boxer loses by decision after 3 rounds.

Answer: (B)

A knockdown is defined by a fighter being knocked to the canvas and unable to rise immediately to continue, which triggers the referee’s count. The purpose is to give the boxer a moment to recover and demonstrate they can continue safely; if the boxer rises before the count ends and is deemed able to continue, the bout resumes. If they cannot rise or cannot continue, it results in a knockout.

This isn’t about being knocked out of the ring, which is a different situation; it isn’t about warnings for holding and clinching, which are separate fouls; and it isn’t about losing by decision after rounds, which describes the fight’s outcome, not a knockdown.
