Two changes take A to B. Apply both of them to C. Which answer figure replaces the question mark?

A is turned $90^{\circ }$ clockwise (the upright L now lies on its side with its foot pointing down) AND its colours are swapped (one orange square becomes three orange squares). Doing both to C — a quarter turn clockwise and swapping orange with white — gives (d). (a) only swaps colours, (b) only turns, and (c) turns the wrong way.
