Check the correct statements on scattering of light. S1 : Rayleigh scattering is responsible for the bluish appearance of sky. S2 : Rayleigh scattering is proportional to \[1/{{\lambda }^{4}}\]when the size of the scatterer is much less than\[\lambda \]. S3 : Clouds having droplets of water (large scattering    objects)    scatter    all wavelengths are almost equal and so are generally white. S4 : The sun looks reddish at sunset and sunrise due to Rayleigh scattering.

A)  S1 only                                

B)  S1 and S2

C)  S2 and S3           

D)  S1, S2, S3 and S4
