The clear sky appears blue because

  1. blue light gets absorbed in the atmosphere
  2. ultraviolet radiations are absorbed in the atmosphere
  3. violet and blue lights get scattered more than lights of all other colours by the atmosphere
  4. light of all other colours is scattered more than the violet and blue colour lights by the atmosphere


The molecules in the air scatter blue light more than red light.

The correct option is C.
