Which of the following correctly defines an accomplice in a crime?

The definition of an accomplice in the context of criminal law pertains specifically to individuals who play a role in facilitating or promoting the commission of a crime, without necessarily being the main perpetrator. An accomplice is someone who actively advises, encourages, or assists another person in committing a crime, which is precisely what option C articulates. This involvement can take many forms, such as providing assistance, resources, information, or moral support, but it is characterized by a shared intent to facilitate the criminal act.

In contrast to this definition, a person who passively observes a crime does not take any active role or show intent to promote the act, thus not meeting the criteria for being considered an accomplice. Similarly, while a person who directly commits the crime would be considered the primary perpetrator rather than merely an accomplice, aiding authorities in capturing a criminal does not align with the characteristics of an accomplice, as this action suggests cooperation with law enforcement rather than participation in the crime.
