Which statement about whistle characteristics is true?

• A. It should be loud enough to be heard by all match participants.
• B. It should be clear enough to differentiate from whistles on other courts.
• C. It should sound decisive enough to show confidence in the calls made.
• D. All of the above

Answer: (D)

Whistle characteristics matter because they enable clear, authoritative communication during a game. A whistle must be loud enough for all participants on the court to hear it promptly, so plays start and stops happen without delay. In venues with more than one court, it needs to be distinct enough to differentiate from whistles used on other courts, which prevents confusion and mixed signals. It should also sound decisive to convey confidence in the calls, helping players react quickly and uphold the flow and fairness of the match. Since all of these factors contribute to effective officiating, the best statement is that a whistle should meet all of these qualities.
