I've got this! VPLS removes the VLAN tag when transporting the frame over the network, but keeps the FCS. The answer is B.

Okay, let me think this through step-by-step. The key is understanding what happens to the VLAN tag and FCS when a tagged frame is received on a null SAP. I believe the answer is B, but I'll double-check my understanding.
