Simple there are some ranges for private address.
10.0.0.0 - 10.255.255.255

172.16.0.0 - 172.31.255.25

192.168.0.0 - 192.168.255.255
in option A first block is 12 so crosses range. option B first block is 168 does not come in to the range. option c first block 172 is ok but second block is 15 but range start from 16 so wrong. option d is correct one

An address is a data structure understood by a network which uniquely identifies the recipient within the network. Addresses in other places than computer networks: Addresses are used by the postal system to allow a postman to find a person's house; to allow a computer to uniquely identify a location in memory.

You should add host addresses for systems that will communicate frequently with the system. You can:

View the entries in the hosts table,
Add an entry to the list of hosts,
Modify the IP address of a host,
Delete a host entry.
