About axis of C.G, means (X, X') axis.
So, the answer is correct.
So, the answer is correct.

Moment of inertia of rectangular section about an axis passing through CG and parallel to width will be b*d^3/12.
And for the section passing through CG and parallel to depth will be d*b^3/12.
So correct answer is option A. d*b^3/12.
And for the section passing through CG and parallel to depth will be d*b^3/12.
So correct answer is option A. d*b^3/12.
