Which sequence of actions marks a workbook as final?

Marking a workbook as final is an action that suggests to other users that the workbook is complete and should not be modified. This is typically done to prevent further changes to the document, promoting its status as a final version.

The correct sequence of actions involves accessing the Backstage view and selecting the Protect Workbook feature. This method is specifically designed for marking the workbook as final and includes options that set the document's status accordingly.

Using the Backstage view is a direct approach that provides an intuitive interface for protecting the workbook and conveying to other users that it should be regarded as complete. By opting for this route, users effectively communicate the intention to halt any editing or modification, thereby reinforcing the integrity of the finalized content.

The other choices presented, while related to protection and saving, do not specifically indicate the correct standard action for marking a workbook as final. They may refer to different functionalities that do not fulfill the requirement for designating a document's final status.
