The blue colour of the sky is due to the:

Correct option is B

Sol. The blue color of the sky is primarily due to the scattering of sunlight by the gases and particles in the Earth's atmosphere.
 This scattering, known as Rayleigh scattering, causes shorter wavelengths of light, such as blue and violet, to be scattered in all directions, making the sky appear blue to our eyes.
 Dispersion is defined as the separation of white light into different colours when the light is passed through the prism.
 The refraction of light is the bending of light rays as they pass from one medium to another, thereby changing the path of the rays.
 Diffraction of light occurs when light waves pass near a barrier and spread out.
