Best answer
The correct option is (d) cpio

Explanation: As a system administrator, you are responsible for creating a backup of the data which resides on your system. For this purpose, there are mainly two backup programs which are extensively used i.e. cpio and tar. The cpio command copies files to and from a backup device.
