From A to B the big shape changes but the small arrow inside does not. Which answer is related to C in the same way?

The big triangle is turned upside down (a half turn) while the small arrow inside still points up and to the right, exactly as before. So in C the big violet pointer turns from pointing right to pointing left, and the small arrow keeps pointing up: (c). (a) turns the whole figure, arrow included; (b) turns only the arrow and (d) gives the big shape a quarter turn.
