What does coercion involve in the context of law?

Coercion in the context of law specifically refers to the act of compelling someone to act against their will by means of threats, intimidation, or physical force. This involves creating a situation where an individual feels they have no real choice but to comply due to fear of harm or other negative consequences. The essence of coercion lies in the use of pressure or the threat of adverse actions to influence someone's behavior or decisions, making option B the most accurate descriptor of this concept.

Other choices, such as encouraging through incentives or offering rewards for compliance, do not encapsulate the coercive aspect, as they imply voluntary cooperation rather than pressure. Similarly, negotiating terms of agreement inherently involves discussion and consent, which contrasts with the fundamental notion of coercion that implies a lack of genuine choice. Thus, the correct answer aligns precisely with the definition and understanding of coercion within legal frameworks.
