Answer is D.
Neighbor Discovery Protocol is an umbrella that defines these mechanisms:
Subsitute of ARP – Since ARP has been removed in IPv6, IPv6 follows a newer way to find the link-layer addresses of nodes on the local link. This new mechanism uses a mix of ICMPv6 messages and multicast addresses.
Stateless Auto-Configuration – This mechanism allows nodes on the local link to configure their IPv6 addresses by themselves by using a mix of ICMPv6 messages and multicast addresses.
Router Redirection – The router sends ICMPv6 messages to an IPv6 node to inform it of the presence of a better router address on the same local link to reach a destination network.
