• Paid features are offered as a monthly subscription and can be managed by the administrator of your AMC account
• Paid features allow advertisers to upload their own first-party insights to better understand the shopping journey
• Paid features provide access to subscription-based tables that can be used in conjunction with the standard tables available in AMC

The correct answer is: Paid features allow advertisers to upload their own first-party insights to better understand the shopping journey

Explanation: Paid features (beta) in Amazon Marketing Cloud are designed to expand the scope and depth of insights through subscriptions powered by Amazon Ads and third-party providers. While AMC does allow onboarding of first-party signals for analysis (using APIs, Event Manager, or integrated signal management tools), the paid features beta specifically do not enable advertisers to upload “insights.” Instead, these features focus on providing additional analytic capabilities or access to third-party insights to help advertisers understand the customer journey. The onboarding of first-party data is a core capability of AMC itself and is not exclusive or unique to paid features beta.
