which of these features lets you control how long user-level and event-level data is stored by google analytics?

The feature in Google Analytics that lets you control how long user-level and event-level data is stored is called the Data retention period. This feature allows you to set the amount of time before user-level and event-level data is automatically deleted from Google Analytics servers. The retention period applies to data associated with cookies, user identifiers (such as User-ID), and advertising identifiers. You can select different retention periods (e.g., 2 months, 14 months, or longer periods for Google Analytics 360 users). This setting helps organizations comply with data privacy regulations and manage data storage efficiently. This feature is accessed in the Google Analytics Admin area under Property settings in Data Settings > Data Retention, where you can choose the desired retention period for event and user data. In summary, the correct answer is the Data retention period feature.
