A P router (Provider router) is located in the core of the service provider's network. Its functions include:
Forwarding MPLS-labeled packets between PE routers.
Not interacting directly with customer routes or routing instances.
Having no knowledge of VPN routing or customer-specific services.
Option C is correct -- P routers sit in the MPLS core, isolated from customer edge.
