Correct answer: C
The question asks to identify the false statement regarding network addressing.
Multicast and broadcast are two different types of addressing. A broadcast address is used to send data to all hosts on a network and is typically represented by setting all host bits to 1. In contrast, a multicast address is used to send data to a specific group of hosts that have joined the multicast group and belongs to a separate range of IP addresses (Class D in IPv4). Therefore, a multicast address is not a special case of a broadcast address.
