Thanks for explaining in an uderstandable manner @Riyas.

In general terms b= width and d or h = depth or height respectively. When loading is applied we consider bd^3/12 (hear loading is parallel to depth) and y=d/2.
Hear in this problem,
Parallel to width is asked making it shifting terms from width as depth (assume that u have rotated your beam)
So hear instead of bd^3 /12 and y=d/2.
V get db^3/12 and y= b/2.
Making Z=I/Y as db^2/6.

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.

Z= (Moment of Inertia )/(Depth of NA).
= (bh3/12)/(h/2)=bh2/6.
= (bh3/12)/(h/2)=bh2/6.

Here, bd^3/12.
Because I xx of rectangular section.
Because I xx of rectangular section.

Section modulus is a geometric property for a given cross-section used in the design of beams or flexural members.
