Mrh, difficult. I mean act 3 is about to end and we have yet to see Sanji start his fight with Queen. Let's say there is enough time before the act ends that he escapes, meets Queen and they start to fight. He will lose like the others and the act will end (or maybe he doesn't even meet Queen and the act ends regardless). At that point there will only be a rematch (act 5 or whatever, Luffy will face Kaido a 3rd and last time and so the allaiance with their matches). At that point we will have Sanji vs Queen and maybe Zoro vs King too with maybe, and that is Sanji's hope, at the end a big fight with everybody vs Kaido (and BM again?) even if that will be a worn out Sanji (like Zoro?) so he will not shine too much. Probably he and Zoro and all the other ones (double fight or not) will end unconscious with Luffy alone leading the fight to conclusion. So for Sanji option B or maybe A but I seriously doubt we will have C.
