Which of the following items is NOT subject to false advertising regulations?

Gifts are not typically subject to false advertising regulations because they are not actively promoting a product or service in the same way that advertising materials like brochures, billboards, and letters do. False advertising laws focus on the claims made in advertising that could mislead consumers regarding the nature, characteristics, or quality of a product or service. Since gifts generally do not make such claims or serve as a direct advertisement, they fall outside the scope of these regulations.

Brochures, billboards, and letters are considered forms of advertising and are therefore regulated under laws against false advertising. These materials are designed to inform or persuade consumers about products or services, and any misleading information in these contexts would be subject to scrutiny under advertising regulations.
