Which correctly describes how the first life on earth could have occurred by spontaneous generations

In an environment without free oxygen, amino acids, nucleic acids, and lipids were able to increase in number. In large amounts, these molecules could have formed simple life forms.

Explanation:

The abiogenesis i.e the origin of life states a hypothesis that primitive life originated from inanimate things. It is believed that before-life, chemical reactions between carbon and water gave rise to life, probably with lightning. Which induced the production of the following chemicals: lipids, carbohydrates, amino acids and nucleic acids. The reaction over a period of time produces the self-replicating molecules of Ribonucleic Acid.

This gives a great tendency for the first life to have been generated from a sporadic increase of amino acids, nucleic acids, and lipids in the absence of oxygen.

i would think the answer is between b and d i would say d sorry if wrong

oh i never knew that
