When does the offensive charged conference end during a meeting with a runner on base?

The end of an offensive charged conference is marked by the coach's actions as they begin to return to their position on the field. This indicates that the meeting with the runner has concluded, allowing the game to resume. The rule is designed to ensure that conferences do not prolong the game unnecessarily and that play can continue effectively once the conversation is finished.

The other options do not capture the moment when the conference officially ends. For instance, simply leaving the field may not indicate that the discussion has concluded, as the coach might have lingering instructions. The action of the runner reaching the next base or an umpire calling a strike are not definitive markers for the end of a charged conference, as the conversation could still be ongoing regardless of those events. Thus, the most accurate scenario for concluding a charged conference is when the coach starts to return to their position.
