Explanation

APIPA (Automatic Private IP Addressing) is a feature in Windows that automatically assigns an IP address when a DHCP server is unreachable. APIPA addresses always fall in the range 169.254.0.1 to 169.254.255.254, with a subnet mask of 255.255.0.0. Option C (169.254.44.157) falls within this range. Option A (4.2.2.2) is a public IP. Option B (10.23.145.90) is a private Class A address. Option D (192.168.32.59) is a private Class C address. An APIPA address indicates the device cannot reach a DHCP server and cannot communicate outside the local subnet.
