A clock showing 10:40 hangs on a wall above a swimming pool. Which panel shows its reflection in the pool?

The water image turns the clock upside down without swapping sides: the orange 12 marker goes to the bottom, the minute hand on 8 moves to the 10 position, and the hour hand near 11 moves near 7: (c). (a) keeps the marker on top, (b) is unchanged and (d) is a half-turn.
