A desk lamp stands on a mirror lying flat on the table (the dashed line at the bottom). Which panel shows the lamp's image in this mirror?

A mirror at the bottom turns the picture upside down but keeps left and right: the base goes to the top, the switch stays on the right, the arm bends the same way and the yellow shade, still on the left, now opens upwards to the left: (d). (c) moves the shade without turning it over; (b) is the image in an upright mirror and (a) also swaps left and right.
