• An AMC advertiser instance
• An AMC account
• A manager account
• An AMC sandbox instance

The correct answer is: An AMC sandbox instance

Explanation: An AMC sandbox instance is the environment that allows you to inspect AMC tables at record level. In AMC sandbox, you can disable aggregation controls and access event-level (non-aggregated) synthetic data, which is not possible in live advertiser instances due to privacy constraints.

Reference content: From Amazon’s official AMC documentation – AMC Sandbox

“AMC sandbox provides functionalities identical to what’s available in AMC advertiser instances, and contains only synthetic signals generated to mimic the structure and statistical properties of AMC signals… Query with Aggregation Controls turned off and inspect non-aggregated reporting in details to inform query understanding and optimization. This view is NOT available in the advertiser instances.”

“You can disable aggregation controls to output event-level information of synthetic signals as part of your query outputs. This helps you to inspect the underlying composition of the reports.”
