  • The process of evolution of life was a very slow process. 
  • Initially, Nitrogen and water vapours were present in the atmosphere. 
  • Then in a very hot temperature, Carbon formed and that led to the formation of Hydrocarbons. 
  • Nitrate was formed by the action of nitrogen and metals. 
  • Nitrates and vapours mixed and formed ammonia gases.
  • Hydrocarbons and ammonia mixed and formed sugar and certain other organic compounds. 
  • This led to the formation of virus-like structures. 
  • Further single-celled, organisms formed and the further processes gradually led to the evolution of life. 

The correct option is Nitrogen, Water vapours.
