Show answer & explanation
Correct answer: B
The correct option is B (Class D). IPv4 addressing is divided into five classes (A to E). Class D IP addresses (ranging from 224.0.0.0 to 239.255.255.255) are explicitly reserved for multicasting protocols, which allow a single source packet to be efficiently delivered to a specific group of destination hosts simultaneously.
