C makes sense too. It’s about 802.1D, not 802.1ag.

I’m leaning towards A. BPDUs are crucial for loop detection.

I think B is correct. The MEP needs to see its own frames.

C is totally right, loops are 802.1D stuff.

I thought it was A? Spanning-tree BPDUs are key!

I vaguely recall that 802.1D deals with spanning tree, so I don't think that's what we're looking for here.

I feel like this question is similar to one we practiced about CFM frames, and I think option B is the right answer.

I remember something about BPDUs in spanning-tree, but I don't think that's related to 802.1ag.

I think loops are detected when the MEP sees its own CFM frames returned, but I'm not entirely sure.
