Solution

The correct option is C Statement-1 is true, Statement-2 is true and Statement-2 is NOT the correct explanation for Statement-1.
Moment of inertia about its centroidal axis has a minimum value as the centroidal axis has mass evenly distributed around it thereby providing minimum resistance to rotation as compared to any other axis. Also the statement-2 is correct but is not the correct explanation for statement-1.
