Step-by-step explanation:
The "svn move oldname newname" command in SVN (Subversion) is used to rename or move a file or directory within the SVN repository. Therefore, the correct answer is: c) Renames the file in the SVN repo. Executing this command updates the versioned history of the file, preserving its change history while reflecting the new name or location. This operation is beneficial for maintaining a clear and organized structure in the version control system without losing track of the file's evolution. It does not revert changes in the working copy, clean the repository history, or remove any file or directory; rather, it specifically handles the process of renaming or moving items within the versioned structure.
