The word GANGA, painted in block letters on a ghat wall, is reflected in the river below it. Which panel shows its water image?

Water reflects top and bottom: the letters stay in the same order G A N G A, but each one is turned upside down (the A's stand on their points, the G's open at the bottom-right): (b). (a) reverses left and right, (c) turns each letter left-to-right, and (d) is a half-turn.
