A student performs the experiment on tracing the path of a ray of light passing through a rectangular glass slab for different angles of incidence. He measures the angle of incidence `anglei`, angle of refraction `angler` and angle of emergence `angle e` for all his observations. He would find that in all cases :

Options

A. `angle i` is more than `angle r` but (nearly) equal to `angle e`
B. `angle i` is less than `angle r` but (nearly) equal to `angle e`
C. `angle i` is more than `angle e` but (nearly) equal to `angle r`
D. `angle i` is less than `angle e` but (nearly) equal to `angle r`
