Explanation:

When importing prospects into Marketing Cloud Account Engagement (Pardot), users have a few important capabilities that support lead management. Assigning prospects to an existing user (A) ensures that the leads are directed to the right sales or marketing representative for follow-up. This is crucial for timely engagement and maintaining accountability. Additionally, users have the option to undelete matching prospects from the Recycle Bin (D), which allows previously deleted prospects to be restored if they match new imports. This avoids unnecessary duplication and ensures data consistency. These two actions streamline the lead import process while preserving historical context.
