C is correct.
Here the load acts on the depth side.
So, the answer is b^2h/6.
Here the load acts on the depth side.
So, the answer is b^2h/6.

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.

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).

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.
