Answer 2

The earth's early atmosphere loses its hydrogen and helium gases because the gases were replaced by carbon dioxide from volcanic eruptions. Thus, the correct option is D.

What was the condition of  Earth's early atmosphere?

The earth's early atmospheric conditions were reduced due to the excess presence of anaerobic organisms in nature.

Due to the lack of oxygen, a massive volcanic eruption occurs in the past time. This leads to the conversion of hydrogen and helium gases to carbon dioxide in the atmosphere.

Therefore, the correct option for this question is D.
