I’m not confident, but I think B could be the answer since it seems like a standard routing protocol setup.

I'm leaning towards D because I recall that MPLS is mainly for core devices, but I could be mixing it up with something else.

I feel like I've seen a similar question before, and it was about MP-BGP. So maybe A is the right choice?

I think the answer might be C, but I'm not entirely sure. I remember something about label signaling protocols being used between PEs and CEs.
