A fault whistled by the second referee is indicated by which method?

The correct method for indicating a fault by the second referee includes both blowing the whistle and using hand signals. This dual approach ensures that the fault is communicated clearly and effectively to both the players and the first referee. The whistle serves as an audible signal that captures immediate attention, while the hand signals provide visual confirmation of the specific fault that occurred, reinforcing the decision made by the second referee. This practice is crucial for maintaining proper game flow and ensuring that all participants understand the call clearly.

In contrast, relying solely on hand signals would not provide the necessary immediate attention that comes with the sound of a whistle, while exclusively blowing the whistle would lack the specificity needed to inform everyone about the type of fault. Finally, written communication to the first referee is not a standard method for signaling faults in live play, as the game relies on real-time communication.
