Final answer:
The agent could be guilty of coercion, which involves pressuring someone to act against their will through threats or force, potentially impairing the claimant's ability to make informed decisions. The correct option is d.
Step-by-step explanation:
Coercion in the context of law refers to the practice of compelling someone to act in an involuntary manner by use of threats or force. It involves a situation where a person is forced to do something against their will.
The agent's action in this scenario can be seen as an attempt to pressure the claimant into signing a release form, which may interfere with the claimant's ability to make a free and informed decision.
Hence, Option d is correct.
