I_{1} = Moment of Inertia of ring of mass M and radius R about its diameter.

I_{2} = Moment of Inertia of Disc of mass M and radius R through central axis perpendicular to plane of ring.

I_{3} = Moment of Inertia of solid cylinder mass M and radius R about its axis.

I_{4} = Moment of Inertia of solid sphere through its diameter.

(1) $I_1+I_2=I_3+{5\over4}I_4$

(2) $I_1=I_2=I_3<I_4$

(3) $I_1 >I_2=I_3=I_4$

(4) $I_1+I_2=I_3+{2\over5}I_4$
