After Team A is awarded an alternating-possession throw-in, when will the arrow switch toward Team B?

The correct option is the one stating that the arrow will switch toward Team B after Team A commits a throw-in violation. In basketball, the alternating possession arrow is a mechanism used to determine which team will receive the next possession when the game is played under certain circumstances, like jump balls or specific situations that might arise, such as a violation during a throw-in.

When Team A is awarded the alternating-possession throw-in, they initially have the opportunity to inbound the ball. However, if Team A commits a throw-in violation—such as failing to properly execute the throw-in, stepping out of bounds, or not adhering to the specific throw-in rules—it indicates that Team A is not following the proper procedures. As a result, the possession arrow will switch to Team B. This adjustment reflects that Team A's violation prevents them from retaining possession, therefore granting Team B the next opportunity.

The other scenarios do not automatically trigger the arrow switch to Team B. For instance, a throw-in pass being touched by a player on Team A or a foul occurring does not change the possession unless there is a violation.
