Final answer:

The cylindrical shell has more kinetic energy compared to the solid cylinder.

Step-by-step explanation:

The cylindrical shell has more kinetic energy compared to the solid cylinder.

Kinetic energy is given by the equation KE = 1/2 * I * ω², where I is the moment of inertia and ω is the angular velocity.

In the given information, it states that the hollow cylinder has the largest moment of inertia for a given radius and mass. Since the moment of inertia is greater for the cylindrical shell, it will have more kinetic energy.

Therefore, the correct answer is b) Cylindrical Shell.
