Section modulus is the ratio of MOI of N.A & Distance from NA from the extreme stressed fibre.
Here NA plays the main role. The load applied in the face of Length x depth. This face elongated & opposite face compressed. So, NA will lie in between this. That means NA will pass perpendicular to width. so MOI will be b^3.d/12.
Distance from n.a. to extreme stressed fibre is b/2.

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.

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.
