D. The IPv6 multicast (one-to-many) address identifies a set of hosts. The packet is delivered to all the hosts identified by that address. This type is similar to IPv4 multicast (Class D) addresses. IPv6 multicast addresses also supersede the broadcast function of IPv4 broadcasts. You use an “all-nodes” multicast address instead. One additional function of IPv6
multicast is to provide the IPv4 broadcast equivalent with the all-nodes multicast group.
From the CCDA 200-310 book-IPv6 reduces unnecessary bandwidth by eliminating the use of broadcasts, replacing them with multicasts.
Answer (D) Multicast is the correct Answer, reference: http://ipv6friday.org/blog/2011/12/ipv6-multicast/
