Two circular discs `A` and `B` of equal masses and thicknesses. But are made of metals with densities `d_A and d_B (d_A gt d_B)`. If their moments of inertia about an axis passing through the centre and normal to the circular faces be `I_A and I_B`, then.

`I_A = I_B`

`I_A gt I_B`

`I_A lt I_B`

`I_A gt = lt I_B`
