The diagram below shows the sequence of events and processes which resulted in the origin of life on Earth.Picture shows a flow chart with a rectangle labeled non-living matter at the top, an oval labeled chemical processes below it, and a rectangle labeled A at the bottom.

The event that best fits the box labeled A is appearance of bacteria. The answer is letter B

Answer: Option (D) is the correct answer.

Explanation:

When a non-living thing undergoes chemical processes then it leads to the transformation of atmosphere.

For example, both oxygen gas and hydrogen gas are non-living things but when they chemically combine with each other then it results in formation of water (\(H_{2}O\)) molecules which helps in transformation of atmosphere.

Whereas cells, bacteria, and plants are all living things which cannot be obtained from a non-living thing.
