A person is not guilty of an offense if conduct is induced by a public officer for obtaining evidence. This is defined as _____.

The concept being described relates to entrapment, which occurs when a law enforcement officer or agent induces a person to commit a crime that they would not have otherwise committed. In legal terms, entrapment serves as a defense that asserts that the defendant's criminal behavior was prompted by someone in a position of authority, making it an unfair action for the government to prosecute.

In this case, when a person demonstrates that their actions were a direct result of inducement by a public officer, it negates the intent that is typically necessary to establish guilt for a crime. The essence of entrapment lies in the idea that the justice system should not penalize individuals who are manipulated into criminal behavior by those tasked with upholding the law.

The other choices do not align with the concept of being induced into committing a crime by a public officer. Self-defense pertains to the justification of using reasonable force in response to a threat, and an affirmative defense generally refers to a claim that, if proven, negates liability. Encampment is not a legal term typically associated with criminal defense. Thus, entrapment accurately reflects the situation described.
