# A round uniform body of radius R, mass M and moment of inertia I, rolls down (without slipping) an inclined plane making an angle $\theta$ with the horizontal.Then its acceleration is :
( A ) $\frac{g\; \sin \theta}{1 - I/MR^2}$
( B ) $\frac{g\; \sin \theta}{1 - MR^2/I}$
( C ) $\frac{g\; \sin \theta}{1 + MR^2/I}$
( D ) $\frac{g\; \sin \theta}{1 + I/MR^2}$
