Moment of inertia of a circular section about an axis perpendicular to the section is

Answer & Solution
Correct Answer: Option C
Moment of inertia for a circular section about an axis perpendicular to the section is given by $$\frac{{\pi {{\text{d}}^4}}}{{32}}$$, where d is the diameter of the circle. Therefore, the correct answer is Option C.

We have to use perpendicular axis theorem, that give (M.O.I)zz=(M.O.I)xx + (M.O.I)yy from that we get option (c) is correct
