How is an accessory defined in relation to crime?

An accessory is defined as a person who assists in the commission of a crime but is not physically present during the crime itself. This means that their involvement may come through various means such as providing assistance, direction, or planning prior to the crime occurring, rather than being an eyewitness or participant in the act itself.

This definition encompasses a wide range of supportive actions that facilitate the commission of the crime, distinguishing the role of an accessory from that of an accomplice, who is typically present during the criminal act. For instance, someone who provides tools, information, or even emotional support to the perpetrator, ensuring the crime can be carried out effectively, would be classified as an accessory.

The other options present definitions that do not align with this understanding. Being present during the crime, providing financial support, or committing the crime alone represents different roles and levels of involvement in criminal activities which do not meet the legal criteria for classification as an accessory.
