A circular hole of radius $$\frac{R}{4}$$ is made in a thin uniform disc having mass and radius $$R$$, as shown in figure. The moment of inertia of the remaining portion of the disc about an axis passing through the point O and perpendicular to the plane of the disc is-

A

$$\frac{219MR^2}{256}$$

B

$$\frac{237MR^2}{512}$$

C

$$\frac{197MR^2}{256}$$

D

$$\frac{19MR^2}{512}$$
