You don’t know how long C has been incorrectly yielding. There may well have been enough time for them both to move onward.
Also there’s nothing to say that A isn’t a yet undiscovered C.
I’m from the UK so roundabouts are second nature. I’ve been an accidental C before. Where I had to wait for a lot of cars that had priority over me. When it finally was open for me I was zoned out. Luckily the car behind me was very polite and just used a short beep of the horn to bring me back to reality.
Car D is going to have to wait for car A no matter what
Assuming no cars come after yellow car, it doesn’t matter if car C goes or not.
Honestly it’s nicer because car D doesn’t have to move up a car length to yield.
Yes they could get screwed very hard though
Well couple of things.

D could take the first exit while signalling
