What is the statute of limitations concerning criminal charges?

The statute of limitations concerning criminal charges refers specifically to the time frame within which a government must file criminal charges against a suspect. This regulation is crucial as it ensures that evidence remains fresh and that defendants are given a fair opportunity to defend themselves in a timely manner. After the statute of limitations expires, the government loses its right to prosecute the case, which serves to promote justice and efficiency within the legal system.

The other options, while related to legal proceedings, do not accurately describe the statute of limitations in this context. The focus is specifically on the time allowed for prosecution to occur rather than procedural matters like questioning witnesses, commencing a trial, or the timing of when a victim reports a crime. Thus, option B correctly captures the essence of what the statute of limitations is designed to enforce regarding the prosecution of criminal charges.
