The first figure of each row is reflected in two different mirrors to give the other two. Which figure completes the bottom row?

The middle figure is the first one reflected in an upright mirror (left and right exchanged), and the third is the first one reflected in a flat mirror (its water image: top and bottom exchanged). The water image of the bottom-left figure moves the triangle up and makes it point down-right, and moves the circle and dot to the bottom-right and top-right: (c). (a) is the upright-mirror image, (b) is a half turn and (d) a quarter turn.
