PATNA is written in tall block letters on a boat-club wall right above the river. Which panel shows the reflection of the word in the river?

The reflection keeps the order P A T N A and turns each letter upside down: the P's loop is at the bottom, the A's point down and the T stands on its bar: (c). (a) turns each letter left-to-right instead, (d) reverses the whole word and (b) is a half-turn.
