Which of the atmospheric pollutant causes general chlorosis destruction of chlorophyll?

• A. SO${}_2$
• B. Hydrocarbons
• C. CO
• D. CO${}_2$

Answer 1

The correct option is A SO${}_2$

The increase in the concentration of the air pollutants results in an adverse effect on the plants and animal health.

The chlorophyll pigments in the leaves of the plants are destroyed in the presence of increased amounts of sulfuric acid which is formed by reacting with the water in plants.

Thus, the correct answer is option A.
