Wait, isn't H-VPLS Hierarchical VPLS? That's not the same as PBB. I'm going with D) MAC-in-MAC.

Hmm, I'm not sure if it's MAC aggregation. That sounds more like link aggregation. I'll go with D) MAC-in-MAC.

I'm pretty sure PBB stands for Provider Backbone Bridges, which is D) MAC-in-MAC. Makes sense since it encapsulates customer MAC addresses within service provider MAC addresses.
