Which of the following is NOT a type of defense?

Negligence is not considered a type of legal defense in the same context as the others listed. Instead, negligence refers to a failure to exercise the care that a reasonably prudent person would exercise in similar circumstances, which can often serve as the basis for a claim in civil litigation rather than a defense in a criminal case.

The other options—compulsion, entrapment, and necessity—are recognized legal defenses that can be invoked in criminal cases. Compulsion asserts that a person acted against their will due to threats of imminent harm. Entrapment involves claims that law enforcement induced the individual to commit a crime they would not have otherwise committed. Necessity argues that the criminal act was justified to prevent a greater harm. Understanding the distinctions among these concepts is crucial for navigating legal principles effectively.
