What is the defense of necessity?

• A. Committing a crime to achieve a personal gain when alternatives exist.
• B. A defense based on moral obligation.
• C. A defense that allows any unlawful act if beneficial.
• D. Committing a crime to prevent imminent harm when no lawful alternatives exist.

Answer: (D)

The defense of necessity applies when you face an imminent threat and you commit an unlawful act to prevent that harm, but there were no lawful options available to avoid the danger. The key idea is choosing the lesser harm in a true emergency, where any action taken is aimed at preventing a greater harm and there isn’t time or opportunity to use legal remedies.

This option matches that idea: you commit a crime to prevent imminent harm when no lawful alternatives exist. It captures the urgency and the absence of better, legal paths, plus the idea that the act is chosen to avert a greater evil.

In practice, the defense also involves reasonable belief that the action was necessary and that the harm avoided outweighs the harm caused, though those specifics can vary by jurisdiction. Other choices don’t fit because they describe motives (personal gain), abstract moral obligation, or a blanket allowance of unlawful acts, none of which align with the legal criteria for necessity.
