Which situation would likely necessitate the use of physical force to overcome resistance?

Using physical force may be necessary when a student refuses to leave a classroom, particularly if their presence disrupts the educational environment and the instructor has made a reasonable request for them to exit. In this situation, the refusal could escalate to a point where intervention is required to maintain safety and order, especially if the student poses a risk to themselves or others.

Choosing to address the situation with physical force is typically seen as a last resort after de-escalation tactics or verbal requests have failed. In contrast, being late to class or making inappropriate comments usually does not warrant such drastic measures, as these situations can often be resolved through dialogue or disciplinary actions without the need for physical intervention. Completing an assignment does not present any conflict or need for intervention, further underscoring why the first scenario is the correct choice.
