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

C. `S_(2) and S_(3)`
D. `S_(1),S_(2), S_(3) and S_(4)`
