A password card shows the code bPq2. Which panel shows exactly what appears in the dashed mirror?

Reverse the order (2 q P b) and turn every character round: the 2 now looks like a 5, the q looks like a p, the P faces left and the b looks like a d: (c). (a) reverses without turning, (d) turns without reversing, and (b) is the code turned upside down, where b becomes q and q becomes b.
