Solution
The correct option is B least
The red color of the sun at the time of sunrise and sunset is because the red color 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, so all the other low wavelength light gets scattered and finally only the red color in the light reaches the observer. As a result, the sun and the region near by it, is seen red.
