I1 = Moment of Inertia of ring of mass M and radius R about its diameter.
I2 = Moment of Inertia of Disc of mass M and radius R through central axis perpendicular to plane of ring.
I3 = Moment of Inertia of solid cylinder mass M and radius R about its axis.
I4 = 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) $I_1+I_2=I_3+{2\over5}I_4$
