Rayleigh scattering and Mie scattering are the types of ________?

Consider the following statement and choose the incorrect one (s).
I. The blue colour of clear sky is due to the presence of atmosphere on the earth.
II. The greyish appearance of sky is due to the presence of smoke and dust particles in the atmosphere.
