Show answer & explanation
Correct answer: B
The correct option is B (1110). In classful IPv4 addressing, Class D addresses are reserved for multicast traffic. They are architecturally identified by setting the four highest-order bits (most significant bits) of the first octet strictly to 1110, establishing a decimal range from 224 to 239.
