I'm not sure about option C, but I think option D is true because the FDB on PE-C should have entries for both CE routers connected to PE-A and PE-C.

I agree with you, Francesco. Option B might also be true because the FDB on PE-B should have an entry for the CE router connected to PE-A.

A successful ping means the FDB on PE-A and PE-C will have entries for the CE routers involved, but PE-B's FDB will only have an entry for the CE router connected to PE-A.
