Answer 2

Answer:

A.zero degree

b. 0

When a ray of light passes through a rectangular glass slab, the emergent ray is parallel to the incident ray produced.

Now, angle of deviation is the angle between the emergent ray and the incident ray produced.

So, these two rays being parallel, the angle of deviation is 0.
