Answer 1

Answer:

Option (d) The light bending inside the glass.

Explanation:

We know that in refraction, as the light travels from an optically rarer to denser medium, the incident light bends at theta angle inside the glass towards the normal.

Later when it is be projected outside, it bends away from the normal making the initial incident ray's extension and emergent ray go parallel.
