A park slide stands under a mirror fixed flat on the ceiling of a play-hall (dashed line). Its ladder is on the left and the orange chute runs down to the right. Which panel shows the slide in the ceiling mirror?

A flat mirror above turns the picture upside down but keeps left and right: the ladder stays on the left, now hanging down from the top, and the chute still runs to the right but rises from the platform instead of falling: (b). (c) leaves the chute sloping down, (a) moves the ladder to the right and (d) does both.
