Many experiments on earths early atmosphere have resulted in formation of organic molecules but have never resulted in cell formation in which of the following ways do the experimental conditions prevent cell formation in the lab?
a. ultraviolet light intensity of early earth cannot be reproduced
b. gas combustion of early earth cannot be replicated
c. the nutrients earlier are different from those found today
d. the experiments cannot last for billions of years as it did on earlier

Option D

Explanation:

The early earth conditions were different from the conditions that exists today. Too much of oxygen in the atmosphere hinders the formation of cells.

Many experiments were performed to form organic compounds but none of them helped to form cells.

This is because after the formation of organic molecule, it took time for the formation of cells. There is no such experiment that can be performed for such a longer duration of time, so cells cannot be formed.
