Which feature allows users to differentiate between various document drafts?

Version comparison is a crucial feature that enables users to identify and differentiate between various drafts of a document. This feature allows individuals to systematically compare changes made to a document over time, highlighting revisions, additions, or deletions. Such functionality is invaluable in environments where multiple versions of a document are created, as it provides a clear visual representation of how the document has evolved. By using version comparison, users can easily track the history of changes, ensuring that they can refer back to earlier versions if needed or understand how particular revisions contribute to the final document.

The other options serve different purposes that are not specifically focused on comparing drafts. Document linking connects documents but does not provide a comparison of their content. Live collaboration allows multiple users to work on a document simultaneously, which can facilitate updates but does not inherently focus on version differentiation. A tagging system helps categorize documents but does not offer a direct method for comparing different drafts. Thus, version comparison stands out as the feature designed specifically for analyzing and differentiating between document drafts.
