Answer

Brief Explanations:

Life - as we know it - requires oxygen for respiration. In Earth's early atmosphere, available oxygen was used to create an ozone layer. This meant there was not enough free - oxygen for life forms to use for metabolic processes, making it difficult for life to exist. The other options do not directly relate to the lack of a key component for life's existence.

Answer:

Available oxygen was used to help create an ozone layer within Earth's atmosphere.
