The given figure shows a disc of mass $M$ and radius $R$ lying in the $x-y$ plane with its center on the $x$-axis at a distance $a$ from the origin. Then,the moment of inertia of the disc about the $x$-axis is:
- A$M\left( \frac{R^2}{2} \right)$
- B$M\left( \frac{R^2}{4} \right)$
- C$M\left( \frac{R^2}{4} + a^2 \right)$
- D$M\left( \frac{R^2}{2} + a^2 \right)$
