(a) Lateral Displacement indeed depends upon the thickness of the glass slab the light has to pass through.
Let's see how...
In this case we have two glass slabs of varying thickness (but same lengths). We can clearly see that the lateral deviation of the light caused by each differs. Due to its greater thickness, the ray of light passing through the slab deviates more as it experiences more refraction. This is because it travels a greater length through the medium compared to the ray of light.
So, the lateral displacement of light depends upon the thickness of the medium, such that, it will be greater if the thickness is more and vice versa.

Explanation:
The lateral displacement is directly proportional to the thickness of the glass slab. ... Now, greater thickness will allow the light rays to travel more distance through the glass slab and the final distance between incident ray and emergent ray,will be also increased.
