The purpose of document locking in file management primarily revolves around ensuring that a document remains unchanged while it is being edited by one user. When a document is locked, it prevents any other users from making modifications to it until the lock is released. This is particularly important in collaborative environments where multiple users may attempt to access and edit the same document. Locking serves to avoid conflicts that could arise from simultaneous edits, which might lead to data loss or corrupt versions of the document.

The other choices may refer to different aspects of document management or collaboration but do not accurately describe the specific function of document locking. For instance, allowing multiple users to edit a document simultaneously contradicts the purpose of locking, which is to single out editing privileges to ensure consistency and control. Similarly, tracking changes and enabling selective viewing encompass broader functionalities within document management systems that might operate independently of the locking mechanism.
