Which feature is used for tracking version changes in reports?

The correct answer, which encompasses tracking version changes in reports, is the Audit Trail feature. The Audit Trail is designed to provide a complete history of changes made to data and reports over time. This feature captures who made changes, what changes were made, and when they occurred, allowing users to track the evolution of a report and understand how and why certain adjustments were implemented.

While the other options refer to similar concepts, they serve different purposes. For instance, Change Log is primarily focused on listing changes but may not provide the level of detail regarding user actions or timestamps that the Audit Trail does. Version Control is generally about managing the different editions of a document or project, while Version History refers to the overall record of versions that exist but may lack the detailed tracking of individual changes as seen in an Audit Trail. Therefore, the Audit Trail stands out as the most relevant feature for tracking version changes in reports.
