According to Section 302A-1141 on corporal punishment, when can reasonable force be used?

The correct answer is grounded in the principle of ensuring the safety and well-being of students. Reasonable force may be used specifically to restrain a student from inflicting harm upon themselves. This aligns with the broader educational philosophy and legal framework that emphasizes the welfare of students, prioritizing their physical safety above disciplinary measures.

In situations where a student is at risk of self-harm, using reasonable force becomes a protective measure aimed at preventing injury. This application of force is considered appropriate and justified in a context where immediate intervention is necessary to protect a student's health and safety.

While the other options may involve scenarios where intervention might be needed, they do not align with the specific legal provisions regarding the use of reasonable force. For instance, using force to discipline a student or prevent disruption may not be considered justified within the same legal framework as the need to protect a student from self-harm.
