Loop-guard shouldn't cause a UFD disabled error, right?

I think option D makes sense because if both a port channel and its members are in the same group, it could cause issues. But I'm not 100% confident.

This seems similar to a practice question we did on spanning tree protocols. I think option B could be the right answer if an interface went down.

I remember studying about uplink-state groups, but I'm not entirely sure how they relate to the UFD disabled error.
