Two circular discs \( A \) and \( B \) are of equal masses and thicknesses but made of metal with densities \( d_{A} \) and \( d_{B}\left(d_{A}d_{B}\right) \). If their moments of inertia about an axis passing through their centres and perpendicular to circular faces are \( I_{A} \) and \( I_{B} \), then
(1) \( I_{A}=I_{B} \)
(2) \( I_{A}I_{B} \)
(3) \( I_{A}I_{B} \)
(4) \( I_{A} \geq I_{B} \)
