D.
Multicasting

Explanation:
Internet Group Management Protocol (IGMP) is a protocol that is used
to report multicast group memberships to routers. When a user chooses to accept
multicast traffic, this means that she becomes a member of a particular multicast
group. IGMP is the mechanism that allows her computer to inform the local routers
that she is part of this group and to send traffic with a specific multicast address
to her system.
