Correct choice is (b) 14° and 40°

Easy explanation: In fixed angles, the tubes are fixed at angle between 14° and 40° to the vertical. Under the influence of centrifugation particles move radially outward and have short distance to travel before colliding withthe outer wall of the centrifuge tube.
