How many overtimes can an NCAA basketball game have?

In NCAA basketball, an overtime period is used to break ties after the regulation game has ended if the score is even. The key point is that there is no limit to the number of overtime periods that can be played. Each overtime lasts for five minutes, and additional overtime periods will continue to be played as necessary until a winner is determined. This ensures that each game has a definitive conclusion and allows teams ample opportunity to secure a victory, regardless of how long it takes.

The other choices imply specific limits on the number of overtime periods, which does not align with NCAA rules that permit as many overtimes as needed.
