Which option correctly matches gas and function?
Answer and explanation
Correct answer: Carbon dioxide — photosynthesis
Carbon dioxide is absorbed by green plants and used as a raw material in photosynthesis. Using light energy, plants convert carbon dioxide and water into glucose and release oxygen, so option B correctly matches the gas with its major biological function. Argon does not support respiration, ozone is chiefly associated with absorbing ultraviolet radiation rather than combustion, and nitrogen does not perform the stated UV-absorbing role. These functions help distinguish important atmospheric gases.
