The FIRST figure of this series is missing. In the figures shown, the orange cell and the blue circle both move round the outer cells at steady rates. Which figure belongs at the start?

From each grid to the next the orange cell moves 2 outer cells clockwise and the blue circle moves 1 outer cell anticlockwise. Working backwards from the second figure (orange top-right, blue bottom-right), the first figure has the orange cell 2 places anticlockwise, at the top-left, and the circle 1 place clockwise, at the bottom-middle: (b). (a) moves the orange cell forwards instead of back, (c) swaps the two and (d) moves the circle the wrong way.
