Please see the work below.

Work Step by Step

We know that rotational inertia is different for different axes of rotation and it can be seen by the parallel axis theorem that is $I=I_{CM}+mr^2$ where $I_{CM}$ is the rotational inertia about the center of mass. This equation also helps us to conclude that the rotational inertia is minimum about an axis passing through the center of mass.
