In a scenario where the batter/runner attempts to return to first base after overrunning it, what happens if tagged while returning?

When the batter/runner overruns first base and attempts to return, they are subject to being tagged out if they are not safely back to the base. In this situation, the batter/runner loses their safe status because they remained off the base and can be put out by the defensive team. Therefore, if the defense tags the runner while they are returning and have not touched the base, the ruling is that the runner is out. This situation illustrates the importance of base running knowledge and understanding the nuances of timing and positioning on the bases during gameplay.

The other options present scenarios that do not accurately reflect the rules and situations regarding base running. For instance, there aren't instances where the batter/runner is always safe upon returning, and the game does not halt while an appeal is being resolved in this context. Additionally, this scenario does not involve a dead ball situation as the play remains live until the runner is either safe or out.
