If light travels faster in water than in glass, refractive index of glass is greater than that of water.
When light enters from 1 to 2, it bends towards the normal, this shows that refractive index of 1 is greater than 2.
As total internal reflection occurs when light enters from 2 to 3, the refractive index of 1 and 2 must greater than 3.
Since the refractive of air must be the least, the answer will be B.
