JEE Main 2023 Physics question on Rotational Motion

$I_{CM}$ is the moment of inertia of a circular disc about an axis (CM) passing through its center and perpendicular to the plane of disc. $I_{AB}$ is it's moment of inertia about an axis AB perpendicular to plane and parallel to axis CM at a distance $\frac{2}{3}R$ from center. Where R is the radius of the disc. The ratio of $I_{AB}$ and $I_{CM}$ is $x : 9$. The value of $x$ is ___________.
