Final answer:
The IP address range reserved for Automatic Private IP Addressing (APIPA) is 169.254.x.x. This range is used when a computer self-assigns an IP address in absence of a DHCP server.
Step-by-step explanation:
The IP address range reserved for Automatic Private IP Addressing (APIPA) is C) 169.254.x.x. When a computer is configured to obtain an IP address automatically, and it cannot reach a Dynamic Host Configuration Protocol (DHCP) server, it will assign itself an IP address from this range. This feature enables a computer to communicate with other devices on the same local network even though it could not obtain an IP address from the DHCP server.
It's important to note that while the other ranges listed, such as A) 192.168.x.x, B) 172.16.x.x, and D) 10.x.x.x, are used for private networks, they require manual assignment or assignment by a DHCP server and are not designated for automatic IP address configuration.
