C makes sense. MTU mismatches can cause connectivity problems.

I feel like B could be the problem too. Authentication issues are common.

I think A is the issue. OSPF needs to be on the CE.

I think it's more likely a mismatch in interface types.

OSPF not configured on the CE is a common issue.

I'm leaning towards the interface types being different. I practiced a question like this, and it seemed to be a common mistake.

The MTU mismatch could be a factor, but I can't recall if it directly affects OSPF. I should double-check that.

I think I saw a similar question where OSPF authentication was the issue. It might be worth considering that option too.

I remember something about OSPF not being configured on the CE router could cause issues, but I'm not entirely sure if that's the main problem here.
