Final answer:
In stateless DHCPv6, the Neighbor Discovery Protocol (NDP) provides router advertisement and prefix information for hosts to self-generate an IPv6 address, with the correct answer being (d).
Step-by-step explanation:
In stateless DHCPv6, the Neighbor Discovery Protocol (NDP) provides certain configuration information to hosts on the network. Specifically, NDP delivers the router advertisement and prefix information necessary for the client or host to generate its own IPv6 address using stateless address autoconfiguration (SLAAC). The answer to the question is (d) Router advertisement and prefix information. This mechanism allows the host to determine the network segment that it is on and to generate a unique address within that segment. Moreover, the router advertisement messages also convey information about the availability of recursive DNS servers though the actual addresses of these DNS servers are typically provided by a separate DHCPv6 server in a stateless configuration.
