Router HW1 Functions as an MPLS LSR Router on the Carrier's

Router HW1 functions as an MPLS LSR router on the carrier's network. The router receives a labelled packet, but the label entry does not exist in the router's LFIB. Given this information, how will the router process the packet?

A) Router HW1 discards the packet.
B) Router HW1 uses the default label to forward the packet.
C) Router HW1 removes the label, searches the FIB, and uses the destination IP address to forward the packet.
D) Router HW1 uses LDP to create an LSP and creates a path in its LFIB for the label carried in the packet.
