Here the first figure of the series is missing. The other four figures follow one rule. Which answer figure belongs in the first box?

From box 2 onwards the heart turns $90^{\circ }$ clockwise each step (its tip points right, down, left, up) and the orange dot moves one corner anticlockwise (bottom-left, bottom-right, top-right, top-left). Going one step backwards from box 2, the heart's tip points up and the dot is in the top-left corner: (b). (a) leaves the heart as in box 2, (c) moves the dot the wrong way and (d) turns the heart the wrong way.
