You are right, Thanks @Amit.

The Answer should be option B.

Debashis said:   7 years ago
About axis of C.G, means (X, X') axis.

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.

Because actually, they asked about the moment of inertia at about Y axis.

No hollow rectangular so answer A is correct.
