Answer 1

Answer:

Carbon: Basis for all living things, every living thing contains this element

Explanation:

The only element that is correctly matched with its description is carbon.

Carbon forms the basis of all living organisms. It is an important component if major biomolecules of life such as carbohydrate, protein, nucleic acids, etc.

Phosphorus is not the most abundant gas in the atmosphere. The most abundant gas is nitrogen, making up about 78% of the atmospheric gases.

Oxygen does not distinguish nucleic acids from other biomolecules and nitrogen is found in other substances apart from storage sites of plants and soils.

The correct option is carbon which forms the basis of all living organisms.
