A potted plant stands on a mirror laid flat on the floor (dashed line). Its stem bends to the right up to a red flower, and a butterfly hovers on the left. Which panel shows the plant's image in this mirror?

A flat mirror below works like water: the image is upside down with left and right kept. The pot is now at the top, the stem bends DOWN to the right to the flower, and the butterfly is still on the left: (a). (b) swaps the sides, (c) is the plant itself and (d) does both.
