The answer is A. Oxygen.

Oxygen is the only element of the answer choices. D. is considered a compound because it's made up of two elements from the periodic table. B. and C. are not considered elements in the periodic table either.

Therefore, the answer is A.

The answer is:
A. Oxygen

Air contains more than one substance, water is chemically made up of oxygen and hydrogen, and sodium chlorine is a mixture of sodium and chlorine.

Hope it helps :)
