AA series of labels from one LER to another LER represent a logical tunnel known as an LSP.

CLabels are locally significant to the MPLS router which means its possible for two routers on the LSP path to use the same label.

B, C, and D are correct. Labels are usually signaled dynamically, can be reused on different routers, and must be unique across the MPLS network. I'm glad they didn't ask about MPLS traffic engineering, that's a whole other can of worms!
