Solution
The correct option is B ii
When white light passes through a prism, it gets dispersed into seven constituent colours, shortly called as VIBGYOR.
Each beam of light has its own particular wavelength and is slowed differently by the glass. Violet light has a shorter wavelength; hence, it is slowed more than the longer wavelengths of red light. Consequently, violet light is bent the most while the red light is bent the least.
