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 Z=I/ymax in general I= bd3/12 in this problem d=b ,b=h.
The loading is in a plane parallel to the side b. ymax= b/2, Z= hb3/12/b/2 =b2h/6.
The loading is in a plane parallel to the side b. ymax= b/2, Z= hb3/12/b/2 =b2h/6.

This question clears out an important concept.
Definition of beam= "a structure member on which load act transversely (i.e perpendicular to N.A)."
Now in question, he said load is parallel to width means that he rotated the beam and now N.A change (because the load will act perpendicular to N.A in the beam).

Z = I/Y.
= bh^2/12 ÷ h/2,
= bh^2/6.
So, the answer is B.
= bh^2/12 ÷ h/2,
= bh^2/6.
So, the answer is B.
