A uniform cylinder of radius R, mass M, and length L rotates freely about a horizontal axis parallel and tangent to the cylinder, as shown below. The moment of inertia of the cylinder about its symmetrical axis is Icm=MR2/2. The moment of inertia of the cylinder about this axis is
A. MR2/2
B. 2MR2/3
C. MR2
D. 3MR2/2
E. 7MR2/5
