The primitive atmosphere of earth contained water vapors, hydrogen, ammonia and
(a) CO₂
Explanation:
The earth was formed approximately 4.5 billion years ago. It emerged as an amalgamation of gas and dust orbiting the sun.
The primitive atmosphere of earth was not fit for the survival of living beings. The air had no oxygen and organisms that could produce oxygen by photosynthesis had not yet evolved.
Carbon dioxide gas was evolved in large amounts by volcanic eruptions and caused an increase in the mean temperature of the planet.
