The fifth of these six figures is missing. Each figure is made from the one before it by the same two changes. Which figure is missing?

From each figure to the next, the whole picture turns $45^{\circ }$ anticlockwise and the arrow and circle swap colours (orange becomes blue and blue becomes orange). Doing this to the fourth figure gives (d), and doing it once more to (d) gives the sixth figure, as it should. (a) forgets the colour swap, (b) turns clockwise and (c) turns twice as far.
