B) Only II
Explanation:
The diagram is missing in the question to show the options. Please find the attached picture for the diagrams. The answer is with respect to the attached pictures only.
When light travels from one medium to another, it generally bends, or refracts. According to Snell's Law, when a ray of light passes through the rectangular slab, and the angle of incidence is equal to angle of emergence, it implies that the incident ray and the emergent ray are parallel to each other.
Hence, option B is correct.
