Selected Answer: C
The Label Distribution Protocol (LDP) can also be secured with MD-5 authentication across the MPLS cloud. This prevents hackers from introducing bogus routers, which would participate in the LDP. https://www.cisco.com/c/en/us/td/docs/net_mgmt/vpn_solutions_center/2-0/mpls/provisioning/guide/PGmpls1.html

The correct answer is D. Since the goal is to prevent fake routers, i.e. hackers, from impersonating the CE, I think you need to use BGP MD-5 authentication on the PE. LDP is used for protection between PE and P, making it difficult for hackers to impersonate PE or P.
