Option B seems the most logical choice here. By configuring the B-VPLS with a Backbone MAC, the customer MAC addresses are hidden from the core, limiting the number of MAC addresses that need to be learned.

I disagree, I believe the answer is D) Each SAP is associated with a common l-MAC to hide customer MAC addresses in the core.
