Correct Option: C

The angle of deviation, by which the light of a particular wavelength gets deviated on passing through a medium, depends upon the refractive index of the medium, as encountered by that light wavelength. The smaller the wavelength of the passing light, the greater is the refractive index observed. As white light passes through a prism, the violet component, having the minimum wavelength observes the maximum refractive index for the prism and, thus, gets deviated to the maximum extent.
