Support B. We're voting for an infobox image here, something that people who aren't active users can look at and refer to. The PNG we use has to be one that is clear and simple, and not too complicated. I would have voted C based on personal preference to the pose, but the PNG we choose shouldn't be based on personal preference, rather based on what is most suitable. I don't know how many users actually think about thay when they vote. The only thing I would change about B is to put it in the correct pallete.
