The word DELHI, written with straight strokes, is reflected in the water below it. Which panel shows the water image?

D, E, H and I are symmetric about their own middle line, so they look unchanged in water; only the L turns over, its foot going to the top. The order stays D E L H I: (d). (a) is just the original word (L not flipped), (c) is the mirror image and (b) is a half-turn.
