Which of the following describes Amazon DSP's capability to delete individual line items within a campaign?

Amazon DSP allows you to delete a line item only if it has not yet started spending. This is a crucial distinction for campaign management. Once a line item begins to accrue impressions or clicks (i.e., starts spending), it becomes part of the campaign's historical record and cannot be individually deleted. This policy ensures data integrity and accurate reporting for campaigns that have been active. While you can pause or archive a line item that has ended or is currently running, deletion is restricted to pre-spend items. Therefore, the option "You can delete a line item that has ended" is incorrect because even an ended line item that has spent cannot be deleted.
