What must a head coach do if they are ejected in the first half of a game?

The correct response is that the head coach must leave the vicinity of the playing area immediately if they are ejected in the first half of a game. This rule is enforced to maintain the integrity and sportsmanship of the game. By removing the coach from the area, it reduces the potential for further conflict and ensures that the game can proceed without disruption.

Remaining near the bench or in the stands would not align with the intent of the ejection, as it could influence players and other coaches or create an unsportsmanlike atmosphere. Waiting until halftime to leave also contradicts the need for immediate compliance with the ejection, as it allows for continued interaction with players and officials, which is prohibited. This requirement supports a fair playing environment and emphasizes the importance of adhering to the rules.
