@Mukesh Yada.
Please explain How y=b/2?
Please explain How y=b/2?

B, because the moment of inertia and section modulus are cross-section properties, not loading properties; i.e., they do not depend upon loading.

The correct Answer must be (bd3/12)/(d/2) which means bd2/6.

Thanks for all the given explanation.

Loading is parallel to side b then neural axis is perpendicular to side b, I about n.a ( n.a is the axis parallel to bending direction by right-hand thumb rule ) when the plane of loading is symmetry.

I think, option B is correct.

Here in the question, it is written that load is in the "plane parallel to side b". Neutral axis should be parallel to b and the correct answer should be option B.

Section modulus = I/Y(max).
Then I = (b^3*h)/12.
And y = b/2.
Then z = (b^2*h)/6.
Then I = (b^3*h)/12.
And y = b/2.
Then z = (b^2*h)/6.
