A) Ring, shell, disc, sphere
B) Shell, sphere, disc, ring
C) Sphere, disc, shell, ring
D) Ring, sphere, disc, shell
Explanation

(c) $I_{Sphere} < I_{Disc} < I_{Shell} < I_{Ring}$
We know that body possessing minimum moment of inertia will reach the bottom first and the body possessing maximum moment of inertia will reach the bottom at last
