Which option correctly gives the dual importance of carbon dioxide?
Answer and explanation
Correct answer: Photosynthesis and greenhouse effect
Carbon dioxide has two important atmospheric roles stated in option D. Green plants use it as a raw material during photosynthesis to manufacture food, while atmospheric CO₂ absorbs outgoing infrared radiation and contributes to the natural greenhouse effect. The gas is not responsible for tides, dust or salinity. Therefore option D correctly combines a biological function with an atmospheric heat-balance function.
