Solution

The correct option is B higher the angle of deviation
Refraction is defined as the bending of light when it travels obliquely from one transparent medium to another.
The angle of deviation is the angle between the incident light and the refracted. Greater refractive index means greater refraction, hence greater angle of deviation.
