A green EXIT sign is shaped like an arrow pointing right. Which panel shows the sign in the dashed mirror?

Both the board and the word are reversed: the arrow now points LEFT and the letters run T I X E from left to right, with the E facing the other way; X, I and T are symmetric: (c). (a) is the sign itself, (b) reverses the letters but leaves the arrow pointing right and the E normal, and (d) is upside down.
