Answer:

A. Oxygen

Step-by-step explanation:

In the primitive atmosphere, oxygen was uncommon. The most abundant chemical compounds in the atmosphere of our primitive planet Earth were ammonia, methane, and hydrogen. Those gases are substrates that favor the formation of carbon, nitrogen, and hydrogen (basic elements of life, including the oxygen in water).

Due to some phenomenons, oxygen becomes more abundant in the atmosphere and life proliferates.
