It's a bad question (is it a Cisco certification by any chance?) I'm going to split hairs and guess the key word is "allocated" which infers "exclusive". So I'd choose (b), since the address represents a group which would be joined by zero or more hosts. As far as I can tell all of the other addresses are valid unicast. Weak question = Weak answer.
