What unlawful practice is Greg guilty of when he misleads Sally about her insurance policy?

The correct answer is misrepresentation. Misrepresentation occurs when an individual provides false or misleading information regarding a material fact related to an insurance policy, which can influence the decision-making of the other party. In this scenario, Greg misleading Sally about her insurance policy constitutes misrepresentation because it involves altering or concealing important information that Sally needs to make informed choices regarding her insurance coverage.

Twisting refers to the act of persuading a policyholder to switch from one insurance policy to another by presenting misleading information, usually about the benefits of the new policy, and can involve misrepresenting the existing policy's terms or benefits. While twisting could potentially apply in a broader context, the specific act of misleading someone about their policy is categorized more directly under misrepresentation.

Coercion involves using threats or intimidation to influence someone’s actions, which is not described in this scenario. False advertising pertains to misleading consumers about products or services, typically in a promotional context, rather than through direct interaction about an individual’s policy. Therefore, misrepresentation is the most accurate description of Greg's unlawful practice in this case.
