Based on sponsored ads campaign policies, prohibited content includes the following:

The correct answer is "References to another company name" because Amazon's sponsored ads policies prohibit the use of competitor names or any other company references in ad content. This rule is in place to prevent misleading or potentially defamatory advertising practices, ensuring that ads remain truthful and fair. Using another company's name in an ad can lead to confusion, misrepresentation, or unfair competition, which goes against Amazon’s guidelines aimed at maintaining a positive and respectful advertising environment. In contrast, references to survey data or product usage, while needing to comply with other guidelines, are not inherently prohibited by the policies, as long as they are accurate and not misleading.
