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.

We are using different methods but same concept. So your process is correct no comment.

If b is width and h is height then section of modulus.
z = I/Y ; I = hb^3/12 and y = b/2 then.
z = (hb^3/12)/(b/2).
Then z = (b^2/6) is answer. Because the load is in a plane to the side b.
z = I/Y ; I = hb^3/12 and y = b/2 then.
z = (hb^3/12)/(b/2).
Then z = (b^2/6) is answer. Because the load is in a plane to the side b.

Section modulus = I/Ymax.
Here I = h*b^3/12.
And Ymax = b/2, then section modulus= (h*b^3/12)/(b/2) = h*b^2/6.
Here I = h*b^3/12.
And Ymax = b/2, then section modulus= (h*b^3/12)/(b/2) = h*b^2/6.

(hb^3)% (0.5b) = (hb^2%6).
