The colours of the shapes follow a cycle, and the shapes also move. Which answer figure is related to C as B is related to A?

From A to B the figure is mirrored left-to-right and every orange shape turns blue, every blue shape turns yellow (and so yellow turns orange). For C: mirror it, so the flag stands on the right with its cloth on the left, then the yellow flag becomes orange, the orange circle blue and the blue triangle yellow: (a). (b) forgets the colours, (c) runs the colour cycle backwards and (d) forgets the mirror.
