B) makes the most sense to me. If the MEP sees its own frames come back, that's a clear sign of a loop.

I'm not sure, but I think option D could also be correct because the record field in the CFM frame tracks chassis-mac addresses.

I agree with Isidra, option B makes sense because the MEP can detect loops by monitoring its own frames.

D) The record field of the CFM frame keeps track of chassis-mac addresses sounds like it could be a cool feature, but it's not how loops are detected in this standard.
