C Correct answer
Explanation

tar -cvf creates an archive (create, verbose, file), while tar -xvf extracts (extract, verbose, file). The syntax requires naming the .tar archive file explicitly before listing files to add. Options A and B show incorrect syntax - they reference 'file' inconsistently and omit the .tar extension or use forward slashes incorrectly.
