Which command in DOS can be used to recover accidentally deleted files?

Solution (By Examveda Team)

To recover accidentally deleted files in DOS, the correct command is UNDELETE. Here's the explanation for each option:
Option A: UNDELETE is the command used to recover accidentally deleted files in DOS.
Option B: DELETE/CANCEL is not a valid DOS command for file recovery. It seems to combine the delete and cancel concepts, which is not how file recovery operates.
Option C: RESTORE is not the correct command for recovering deleted files in DOS. It doesn't perform file recovery operations.
Option D: RECOVER is not the correct command for file recovery in DOS. It typically refers to recovering data from damaged disks, not recovering deleted files.

Therefore, Option A (UNDELETE) is the correct command to recover accidentally deleted files in DOS.
