Which of the following is NOT a violation under the Missouri Merchandising Practices Act?

The Missouri Merchandising Practices Act (MMPA) is designed to protect consumers from unfair and deceptive business practices. It includes a range of prohibitions against deceptive actions such as lying, concealing important information, and failing to disclose material facts that could influence a consumer's decision.

In this context, "deception" involves providing false or misleading information; "concealment" refers to hiding important information that a consumer would need to make an informed choice, and "omission of material facts" means failing to provide information that is crucial to the transaction, which could mislead the consumer.

The option concerning the "disclosure of financial details" does not fall under the violations mentioned in the MMPA because it pertains to the act of providing relevant information to the consumer regarding financial aspects of a transaction. Disclosing financial details can be a required and ethical practice, reflecting transparency rather than deception. Thus, while deception, concealment, and omission of material facts are all actions that violate the MMPA, the act of disclosing financial details is not a violation and may actually uphold the standards encouraged by the Act.
