Which defense is exemplified by 'Duress'?

Duress is a legal defense that occurs when a person commits an unlawful act because they believe they are in imminent danger of harm or death, leading them to act against their will or better judgment. This coercion undermines free will, as the individual feels compelled to commit an act they would not typically engage in due to the immediate threat.

In the context of the options provided, the concept of coercion directly aligns with the definition of duress. The essence of this defense resides in the idea that the individual had no reasonable choice but to act as they did, making it a compelling argument in criminal law cases. The other options do not accurately capture the specific nature of duress; they pertain to different legal concepts that do not involve coercive forces leading to a criminal act.
