Answer: D

Explanation:

IPv6 nodes (hosts and routers) are required to join (receive packets destined for) the following multicastgroups:

– All-nodes multicast group FF02:0:0:0:0:0:0:1 (scope is link-local)

– Solicited-node multicast group FF02:0:0:0:0:1:FF00:0000/104 for each of its assigned unicast and anycastaddresses

IPv6 routers must also join the all-routers multicast group FF02:0:0:0:0:0:0:2 (scope is link-local). The solicited-node multicast address is a multicast group that corresponds to an IPv6 unicast or anycastaddress. IPv6 nodes must join the associated solicited-node multicast group for every unicast and anycastaddress to which it is assigned. The IPv6 solicited-node multicast address has the prefix FF02:0:0:0:0:1:

FF00:0000/104 concatenated with the 24 low-order bits of a corresponding IPv6 unicast or anycast address(see Figure 2). For example, the solicited-node multicast address corresponding to the IPv6 address2037::01:800:200E:8C6C is FF02::1:FF0E:8C6C. Solicited-node addresses are used in neighbor solicitationmessages
