Option B seems tempting, but I'm not sure that's the case. The diagram suggests there might be some connectivity, so I'll need to think this through carefully.
But the traffic from devices behind R2 will go through R4 to reach R3, so it makes sense for the MAC addresses to be associated with the sdp between R3 and R4.
