client from a pool of addresses?

A.
Stateless autoconfiguration.

B.
Stateless configuration.

Stateful autoconfiguration requires a server. If it is stateful, state is accomplished from the server,
if it is stateless, then client generates its own IP address.

B: Stateless and Stateful refer to autoconfiguration, not configuration.
D: Stateless and Stateful refer to autoconfiguration, not configuration.
