Moment of inertia of a ring of mass \( m=3 \mathrm{gm} \) and radius \( r \) \( =1 \mathrm{~cm} \) about an axis passing through its edge and parallel to its natural axis is [CMEET Bihar 1995; JIPMER 2000]
(a) \( 10 \mathrm{~g}^{-\mathrm{cm}^{2}} \)
(b) \( 100 \mathrm{~g}-\mathrm{cm}^{2} \)
(c) \( 6 \mathrm{~g}-\mathrm{cm}^{2} \)
(d) \( 1 \mathrm{~g}-\mathrm{cm}^{2} \)
