Moment of inertia flat disc is given as

I_{disc} = \frac{1}{2}mR^2

moment of inertia of solid sphere

I_{sphere} = \frac{2}{5}mR^2

moment of inertia of hollow sphere

I_{hollow} = \frac{2}{3}mR^2

all the three objects are given with same mass and same radius

so largest moment of inertia is for Hollow Sphere
