If A-1 is disqualified and the official instructs the timer to start the 20-second clock, is this action correct?

The statement is correct because when a player is disqualified, the opposing team is typically granted a specific amount of time to attempt a shot or execute a play before they must take action. In this instance, if A-1 is disqualified, the proper procedure is for the official to instruct the timer to start the 20-second clock. This 20-second clock allows the team to regroup and make necessary adjustments following the disqualification.

This procedure ensures that the game continues at a reasonable pace, preventing delays after a disqualification, and maintains the flow of the game. Utilizing the 20-second clock is a standard protocol in basketball officiating and is applied regardless of whether the disqualification results from a technical foul or any other reason. Thus, instructing the timer to start the clock in this scenario is appropriate.
