The hand turns clockwise by an amount that depends on the dots in the corner, and the dots change too. Which frame comes next?

Each step the hand turns clockwise by $45^{\circ }$ for every dot in the frame before, and one dot is added. With 1 dot it turns $45^{\circ }$ (up to up-right), with 2 dots $90^{\circ }$ (to down-right), with 3 dots $135^{\circ }$ (to left). Now there are 4 dots, so it turns $180^{\circ }$ to point right, and the frame gets 5 dots: (c). (a) does not turn the hand, (b) forgets the new dot and (d) turns only $135^{\circ }$ again.
