This question is really testing our knowledge of the optical layer. I hope I don't get a case of 'tunnel vision' during the exam!

I'm going with C. An ODU LSP is routed between two photonic layer nodes, which makes sense in an OTN-based GMPLS network.

D seems like the right answer to me. The routing of ODU frames is based on their label, just like with other MPLS-based protocols.
