Which option is selected to ensure you are not billed at multiple rates during document promotion?

The option to select in order to ensure that you are not billed at multiple rates during document promotion is "Links only." By choosing to promote only the links, you effectively avoid the additional costs that could be incurred by creating multiple physical copies or versions of the same document. This method allows for a streamlined approach where the documents retain their original location and attributes, leading to a clearer billing process that is straightforward and avoids unexpected charges associated with duplicating documents or changing their classification.

The other options, such as promoting physical files or moving existing documents, can lead to instances where multiple rates might apply, especially if those operations would redefine how documents are classified or related to their billing structure. Therefore, selecting "Links only" is a strategic decision to maintain cost efficiency while managing document promotions effectively.
