The correct answer is (d) 203.0.113.10.

Public IPv4 addresses are globally routable and assigned by IANA (Internet Assigned Numbers Authority) or regional registries. They are used for communication between different networks on the internet. The given options are examples of private and public IPv4 addresses:

  • Private IPv4 addresses are reserved for local networks and are not routable on the internet. They include:

    • 10.0.0.0 – 10.255.255.255 (10.x.x.x)
    • 172.16.0.0 – 172.31.255.255 (172.16.x.x to 172.31.x.x)
    • 192.168.0.0 – 192.168.255.255 (192.168.x.x)

  • Public IPv4 addresses fall outside these ranges and are globally unique. The correct option, 203.0.113.10, is a valid public IPv4 address.
