I'm going with B. The interface facing the neighbor is down, so the router can't see the neighbor. Simple as that.

I'm going with D. If the router hasn't received a valid OSPF Hello packet, it wouldn't show any neighbors.

But if the router hasn't received a valid OSPF Hello packet, how can it form a neighbor relationship?

Wait, I've got it! The router must be out of snacks. Can't establish neighbors on an empty stomach, am I right? Haha!

It could be because the interface is in a different area than the neighbor router.

Hmm, I'm not sure. Perhaps the interface is down or the router hasn't received a valid OSPF Hello packet. Those seem like more plausible causes.

Yeah, not receiving a valid OSPF Hello packet could also be the issue.

I think the answer is C. If the interface is in a different area than the neighbor router, it won't be able to establish a neighbor relationship.
