Answer

AThe vertical axis theorem applies only to.To the plane of the body.These bodies are flat and of very little thickness.Negligible thickness.Therefore, this theorem does not apply to spherical situations.according to this theoremThe moment of inertia of a plane object.The axis perpendicular to its plane is equal to the sum of its moment of inertia.There are two vertical axes on the plane of the body.  Therefore, the sphere is the correct answer.
