• Prohibited practice
• Restricted content
• Misrepresentation of self or product
• Return policy

The correct answer is: Misrepresentation of self or product

Explanation: The misrepresentation of self or product policy under Shopping ads emphasizes transparency and reliability. When users encounter a Shopping ad, there’s an expectation that the advertised product aligns with the actual product on the website. In this case, advertising a price for a single dining chair, while charging for a set of six chairs upon purchase, is a clear violation of this policy. Such inconsistencies mislead customers and breach the principle of representing products accurately and fairly.
