The word PLAY is placed above a mirror lying flat on the table (dashed line). Which panel shows its image in this mirror?

A horizontal mirror keeps the left-to-right order P L A Y but turns each letter upside down: the P's loop goes to the bottom, the L's foot to the top, the A becomes a V-like shape with a bar and the Y's tail points up: (b). (d) forgets to turn the Y; (a) also reverses the order and (c) is the upright-mirror image.
