What occurs if a throw-in by A1 enters the basket before touching another player?

When a throw-in by A1 enters the basket without touching any other player, the ball becomes dead immediately. In basketball, a throw-in is a method of putting the ball back in play and is not considered a typical shot attempt. According to NFHS rules, for a throw-in to be valid and count, it must involve the ball being in play and not scoring directly in this manner. Therefore, if the ball goes in without making contact with another player first, the play is considered dead, and the points do not count.

The other options involve different scenarios that do not apply here since the action described is specifically covered by the rule pertaining to throw-ins. The score does not count, a repeat of the throw-in is not required, and there is no change of possession awarded to the opposing team as a result of this play. Thus, acknowledging that the ball is deemed dead is essential in understanding the outcome of this situation as per NFHS basketball rules.
