Correct answer: C
Explanation: IP address classes are commonly determined by the value of the first octet.
Class A: first octet 1–126 (1.0.0.0 to 126.255.255.255). Note that 127.x.x.x is reserved for loopback.
Class B: first octet 128–191 (128.0.0.0 to 191.255.255.255).
Class C: first octet 192–223 (192.0.0.0 to 223.255.255.255).
Class D: first octet 224–239 (used for multicast).
The address 223.255.255.255 is the final address in the Class C range (192.0.0.0 to 223.255.255.255), so it belongs to Class C.
