Solution
The correct option is B least
Red colour of the sun at the time of sunrise and sunset is because red colour is least scattered. According to Rayleigh's law, the intensity of scattered light varies inversely as the fourth power of its wavelength. When wavelength increases, the intensity of scattering light decreases. Here, Red colour has maximum wavelength and hence it is scattered least.
