What offense occurs when someone alters, destroys, or hides evidence during an investigation?

The correct answer is tampering with or fabricating physical evidence, as this specific offense directly addresses the actions of altering, destroying, or hiding evidence in the context of a criminal investigation. Such actions interfere with the legal process and undermine the integrity of the inquiry or trial. Tampering with evidence can obstruct justice and create significant challenges for law enforcement as they work to gather truthful and complete information.

The other options do not encapsulate the behavior described in the question. A false report pertains to providing untrue information to law enforcement, resisting arrest involves non-compliance with a law enforcement officer's attempts to arrest, and impersonating a public servant involves falsely presenting oneself as an official in authority. Each of these offenses is distinct from the act of altering or concealing evidence, which is a specific crime aimed at protecting the integrity of the investigative process.
