None of the above

Detailed explanation-1: -Hosts that receive particular multicast data are called multicast clients. The multicast clients use services requested by a client program to subscribe to the multicast group. Each multicast group is represented by a single IPv4 multicast destination address.
Detailed explanation-2: -Hosts that want to receive multicast traffic will use the IGMP protocol to tell the router which multicast traffic they want to receive. Our router knows that it has to forward the multicast traffic since a host used IGMP to tell the router it is interested.
Detailed explanation-3: -A source host sends data to a multicast group by simply setting the destination IP address of the datagram to be the multicast group address. Any host can become a source and send data to a multicast group.
Detailed explanation-4: -Multicast. Multicasting is defined as a single source sending to multiple recipients on a network when the receiver broadcasts a signal for acceptance. Multicasting has its own Class D IP addressing scheme, controlled and assigned by the Internet Assigned Numbers Authority (IANA).
