Correct answer is D. If destination is known packet is discarded, if the packet is unknown its flooded to attached CEs.

When a PE router receives a packet from another PE router, it first determines whether it has the destination of the VPLS packet in the appropriate routing table. If it does, the PE router either forwards the packet or drops it depending on whether the destination is a local or remote CE device: If the destination is a local CE device, the PE router forwards the packet to it. If the destination is a remote CE device (connected to another PE router), the PE router discards the packet. Since the destination is not connected to PE-B, it will discard the packet. Answer D is correct
