Suggested Answer: D

The data is transparently carried from end to end: This statement is not true, MPLS does not provide data transparency, which means that the data is not carried unmodified from end to end. MPLS uses labels to forward data, so the original IP packets are encapsulated in new MPLS packets, and the original IP headers are not visible at the egress LSR.

I think option C is not valid because it mentions VRF import policy for VPRN service.
