What feature allows users to track changes and comments in Google Docs?

The correct choice, Version History, is a key feature in Google Docs that enables users to track changes made to a document over time. This feature provides a comprehensive view of all edits and modifications, associated with timestamps and the names of the users responsible for those changes. Users can easily navigate through different versions of the document, see who made specific edits, and even restore previous versions if necessary.

Version History is particularly useful for collaborative work environments, where multiple users may be contributing to a document. It enhances transparency and accountability, allowing users to understand the evolution of the document and to audit changes. This tracking capability makes it easier to review who contributed what, thus fostering better collaboration and management of the document throughout its development.
