Four of these five figures are the same figure turned into different positions; one cannot be obtained by turning. Which is the odd one out?

Hold the arrow so it points up: in (a), (b), (d) and (e) the dot then sits to the right of the arrow's tail. In (c), turned so the arrow points up, the dot is on the LEFT of the tail — it is a mirror image, and no turn can produce it. So (c) is the odd one out.
