HOWRAH is painted in block capitals on a station wall right beside a still pond. Which panel shows the word reflected in the pond?

Water keeps the order H O W R A H but turns every letter upside down. H and O are unchanged, W becomes an M-like shape, R hangs with its loop at the bottom and A stands on its point: (b). (c) leaves the R upright, (d) reverses the word and (a) turns it upside down and reverses it.
