Explanation

A physical interface refers to a physical port on the router (e.g., port 1/1/1). It can be configured with IP addresses, associated with services (e.g., IES, VPRN), and connects to other routers or customer devices. System and loopback interfaces are logical interfaces, not physical. Option D is FALSE, because a physical interface cannot be of type "system" or "loopback" -- those are virtual/logical interfaces in the Nokia router architecture.
