An image consists of three concentric circles, each divided into four quadrants (Top-Left, Top-Right, Bottom-Left, Bottom-Right). Initially, the Top-Right quadrant of all three circles is shaded black. Then, the outer circle's shaded quadrant rotates 90 degrees clockwise, the middle circle's shaded quadrant rotates 180 degrees, and the inner circle's shaded quadrant rotates 90 degrees counter-clockwise. Which quadrants of the three circles are now shaded black?
