Answer:
The rolling sphere with a lower rotational moment of inertia per unit mass than the 2 cylinders puts less of the potential energy released by falling into rotational kinetic energy and more into linear motion kinetic energy so it falls faster.
It all depends on the moment of inertia. Acceleration is inversely proportional to moment of inertia , as we know that radius and mass of all three is equal and the fact that M.I. is less for sphere .That's why it will reach fastest
