I’d say B sounds the best, but it’s still odd. For one thing, “way” usually implies a strategy or course of action, so I get the impression that the rain is somehow controllable. And the overall structure feels a bit forced. Why not “The show will only be canceled if it rains”? (Or to be fastidious about scope: “The show will be canceled only if it rains.”)

Trying to preserve the original structure, I land on this: “The only thing that could cause the show to be canceled is rain.”
