Can access to a Google Doc be revoked once granted?

Access to a Google Doc can indeed be revoked once it has been granted. This means that if a user has shared a Google Doc with others, the owner of the document has the ability to change the sharing settings at any time. They can remove access for specific individuals or groups, effectively revoking their ability to view or edit the document.

This flexibility ensures that document owners maintain control over their content and can adjust permissions as needed based on changes in circumstances, collaboration needs, or security considerations. Therefore, the correct answer highlights the dynamic nature of sharing permissions within Google Docs, allowing for adjustments and enhanced document management.
