Detailed Solution

Acceleration, $a = \frac{g \sin θ}{1 + \frac{I}{m r^{2}}}$

For a sphere, $\frac{I}{m r^{2}} = \frac{2}{5}$

Hence, $a = \frac{5}{7} g \sin θ = constant.$

Hence, speeds of all spheres will be same at the bottom. Sphere (ii) has the largest mass.

Hence, it will have the maximum kinetic energy.
