Solution
The correct option is A Total internal reflection
When the angle of incidence of a ray is greater than the critical angle, the reflected ray is in the same medium, i.e. the light is totally reflected in the same medium. This is known as total internal reflection.
The angle of incidence of a ray for which the angle of refraction is 90∘ is called critical angle.
