Prosecution may be commenced by which of the following?

Prosecution may indeed be initiated through a sworn affidavit, which is a written statement confirmed by oath or affirmation, typically used as evidence in legal proceedings. This means that if there are sufficient facts to support criminal charges, a sworn affidavit can serve as the basis for starting the prosecution process, particularly in cases where law enforcement or a prosecutor seeks to establish probable cause for an arrest or further legal action.

In contrast, a complaint involves a formal charge made in court, typically initiated by a private party rather than being based solely on law enforcement's verification. An information is a formal accusation of a criminal offense, filed by a prosecutor, which does not require a grand jury. An indictment, on the other hand, is an accusation that comes from a grand jury, requiring a more formal investigative process.

The establishment of a prosecution through a sworn affidavit allows for quicker legal actions based on immediate evidence, showing its critical role in the criminal justice system.
