The address range 224.0.0.0/24 falls within the Class D IP address range (224.0.0.0 to 239.255.255.255), which is reserved for multicast traffic. Multicast addresses are used for the delivery of information to multiple destinations simultaneously, making them ideal for applications like audio and video broadcasting. The other options (172.16.0.0/24, 192.168.0.0/24, and 240.0.0.0/24) are not suitable for multicast as they are within different IP ranges used for other purposes (private addressing and future use, respectively).
