It cannot be A because it starts drawing a circle with the center of (4, 1). None of the circles ahve a center at (4, 1). It is B because while it does start at (4, 1), the repeat function adds one to the y and radius. While ti repeats 3 times it ends up drawing all 3 circles. C also works because it starts by drawing the biggest circle and then subtracting the values to make the other two. It cannot be D because in the repeat function it subtracts from the y value and radius too early, it doesn't draw the biggest circle.
