Angular momentum and torque

Two objects, A and B, are both released from rest at the same time from the top of a ramp. Object A is a solid cylinder, and Object B is a hollow cylinder. Assume that both objects roll without slipping down the ramp. The mass, the radius, and the moment of inertia of both objects are found in the table below.

Object	Mass	Radius	Moment of inertia
A	$M$ ‍	$R$ ‍	$\frac{1}{2} M R^{2}$ ‍
B	$M$ ‍	$\frac{1}{2} R$ ‍	$M R^{2}$ ‍

Which object will be the first to reach the bottom of the ramp?
