(A) ∠i and ∠r
(B) ∠i and ∠e

उत्तर
In the given diagram, the angle of incidence (∠i) and the angle of emergence (∠e) have been correctly marked.
Hence, the correct option is B.
Disclaimer: In the question paper the angle of emergence ∠e is drawn incorrectly as it is shown between the normal and the surface of the prism.
