Which of these BEST explains how the emission of pollutants such as carbon dioxide, sulfur dioxide, and nitrogen oxide from a factory into the air may harm organisms that live on land or in water?A. The pollutants may react with water vapor to form
acid precipitation, which harms land plants and aquatic organisms.
B. The release of carbon dioxide into the sir causes an increase in carbon dioxide levels, making photosynthesis difficult.
C. Nitrogen oxide released into the air joins with water vapor to form nitrogen-rich rain (fertilizer) that stimulates plant and algal growth.
D. Sulfur dioxide increases the growth of water plants, crowding out fish.
