RA needs to create a neighborship by using RC's loopback for LDP. RA does not have any route to RC's loopback via CEF table. Answers does not make sense to me. B -- i would think this is the answer as well, as we don't even see RA receiving any LDP hellos -- D -- ww don't need router-id lo0 on RA as the question does not ask for it. Question is only asking C to use the loopback. Because we don't receive any hellos from RC, we have to assume mpls ip is not configured on that interface. Therefore, making the answer B.
