The correct answer is C. OSPFv3.
OSPFv3 (Open Shortest Path First version 3) is an IPv6 routing protocol that is used to exchange routing information within an autonomous system (AS). OSPFv3 is a link-state protocol that uses multicast addresses to send updates.
OSPFv3 uses multicast group FF02::5 to send hello messages and multicast group FF02::6 to send link-state updates. Additionally, OSPFv3 uses multicast group FF02::9 to send OSPFv3 specific link-state updates, such as router LSA (Link State Advertisement) and network LSA.
Static routing is a routing configuration in which network administrators manually configure the routing table. RIPng (Routing Information Protocol next generation) is a distance-vector routing protocol that is used to exchange routing information within an IPv6 network. RIPng uses multicast group FF02::9 to send updates.
IS-IS (Intermediate System-to-Intermediate System) for IPv6 is a link-state routing protocol that is used to exchange routing information within an autonomous system. However, it uses multicast group FF02::14 to send updates.
In summary, OSPFv3 uses multicast group FF02::9 to send OSPFv3 specific link-state updates, such as router LSA and network LSA.
