IP address classes are determined by the value of the first octet. Class A: 1–126, Class B: 128–191, Class C: 192–223, Class D: 224–239 (multicast), Class E: 240–255 (reserved). Evaluating the options: 23.x.x.x is Class A, 127.x.x.x is the loopback range (reserved Class A), 131.x.x.x is Class B (128–191), and 197.x.x.x falls within 192–223, making it a Class C address.
