Two spheres, with masses m and 3m, are connected by a rod of negligible mass, as shown. Three rotational axes are labeled in the figure. Axis B passes through the center of mass of the spheres-rod system, which is represented by the dot, and axes A and C are both a distance d from Axis B. If the same torque is exerted on the system as it rotates about each of the three axes, which of the following correctly compares the angular accelerations αA, αB, and αC of the spheres-rod system about axes A, B, and C, respectively?
