A square, a circle and a triangle are drawn one inside another, and one of them is coloured. How does the colour move from A to B? Which answer goes with C?

From A to B the colour moves one shape inwards: from the outer square to the circle. In C the circle is blue, so the colour moves in to the triangle, keeping its blue colour: (c). (a) moves it outwards, (b) colours two shapes and (d) changes the colour to orange.
