In which of the following situations may a private citizen make an arrest?

A private citizen may make an arrest under specific conditions as defined by law. The correct option encompasses various scenarios where the citizen has the authority to act.

When a felony has been committed and there is clear reason to believe that a suspect has committed it, such citizens are often empowered to intervene. Moreover, if the individual possesses reasonable cause to believe a felony has been committed alongside reasonable cause to suspect who the perpetrator is, this justifies their action. Similarly, circumstances regarding an escaped convict or someone violating parole or probation also grant individuals the right to detain that person temporarily.

Thus, all these situations highlight a citizen's capacity to make an arrest, reflecting broad legal authority granted to them in protecting public safety and aiding law enforcement when necessary. This comprehensive understanding ensures that private citizens act within the bounds of the law, contributing effectively when law enforcement may not be immediately available.
