Which of the following is NOT a deceptive trade practice?

Disclosing all known information in an advertisement aligns with ethical advertising practices and regulations designed to protect consumers. This transparency is crucial in building trust and ensuring that consumers have all the necessary information to make informed decisions. Unlike the other options, which involve deceptive practices that can mislead consumers, full disclosure is a key element of responsible advertising. By providing complete information, the advertisement promotes fair competition and helps consumers avoid potential deception, making it clear that such practices are not considered deceptive.
