While working with MS-DOS, which command is used to undelete a bunch of files with extension DOC that you have just deleted? A. UNDELETE B. UNDELETE *.DOC C. UNDELETE/ALL D. UNDELETE/LIST E. None of the above

The correct answer is: B. UNDELETE *.DOC

The UNDELETE command is used to undelete files that have been deleted from a disk. The .DOC extension is used to identify files that have the .DOC file extension. Therefore, the command UNDELETE .DOC will undelete all files that have the .DOC file extension.

The other options are incorrect because they do not specify

the *.DOC extension. Option A, UNDELETE, will undelete all files that have been deleted from the disk. Option C, UNDELETE/ALL, will undelete all files that have been deleted from the disk, regardless of their extension. Option D, UNDELETE/LIST, will list all of the files that have been deleted from the disk. Option E, None of the above, is incorrect because it does not specify a command that will undelete a bunch of files with extension DOC that you have just deleted.
