It is correct to say that the total kinetic energy of the solid sphere is

less than the total kinetic energy of the cylinder

Explanation:

The correct option is; answer is Option (A) - is less than the total kinetic energy of the cylinder because moment of inertia of solid cylinder (0.5 mr²) is higher than moment of inertia of sphere (0.4 mr²), as such, total energy of sphere will be less than the solid cylinder.
