In your laboratory you trace the path of light rays through a glass slab for different values of angle of incidence (∠i) and in each case measure the values of the corresponding angle of refraction (∠r) and angle of emergence (∠e). On the basis of your observation your correct conclusion is:

(A) ∠i is more than ∠r, but nearly equal to ∠e

(B) ∠i is less than ∠r, but nearly equal to ∠e

(C) ∠i is more than ∠e, but nearly equal to ∠r

(D) ∠i is less than ∠e, but nearly equal to ∠r
