Final answer:
An arrest without a warrant in the presence of an officer is required when a felony is being committed, according to the Code of Criminal Procedure.
Step-by-step explanation:
According to the Code of Criminal Procedure, the event which requires an arrest in the presence of an officer, even without a warrant is Option 2) Committing a felony. A felony is generally a more serious crime that involves more severe penalties. The law allows police officers to make an arrest without a warrant for felonies committed in their presence. The other options, committing a misdemeanor, displaying suspicious behavior, and engaging in a civil dispute, do not automatically necessitate an arrest without a warrant. However, these situations may still warrant an arrest under specific circumstances, which can be guided by the officer's discretion and the specifics of the situation.
