The correct answer is A. Restore files from disks made using the BACKUP command.
The RESTORE command is used to restore files from disks that have been backed up using the BACKUP command. It can also be used to restore files that have been deleted from a disk. However, it cannot be used to restore files that have been deleted from the recycle bin.
The BACKUP command is used to create a backup of files on a disk. The backup can be stored on another disk, on a network drive, or on a tape drive. The RESTORE command can be used to restore the files from the backup to the original disk or to a different disk.
The recycle bin is a temporary storage location for files that have been deleted. The files in the recycle bin can be restored to their original location by clicking on the “Restore” button. However, if the recycle bin is emptied, the files will be permanently deleted and cannot be restored.
