The dashed frame shows a station name board exactly as Nisha sees it in a mirror. Which panel shows how the name is really written?

Reflecting a mirror image again gives back the original: reverse the order and flip each letter. The name reads B H O P A L with the B, P and L facing the normal way: (a). (b) copies the mirror picture as it is, (c) only fixes the order, and (d) turns it upside down.
