Conversions measured via Events Manager can be made available for querying in AMC.

The correct answer is True because conversions measured via Events Manager can indeed be made available for querying in Amazon Marketing Cloud (AMC). Events Manager is a tool used to track and manage conversion events, such as purchases or other user actions, within Amazon's ecosystem. These conversion events can then be made accessible for analysis within AMC, allowing users to query and analyze them alongside other campaign and performance data. By integrating Events Manager with AMC, advertisers can gain deeper insights into how their campaigns are driving conversions and use this data to optimize their strategies. This connection enables a more comprehensive view of campaign performance and conversion tracking.
