Option (D)

Explanation:

There has been a direct relationship between air pollution and asthma. The polluted air is comprised of toxic substances that include the gases and dust particles. These particles directly affect the respiratory tract of an organism. When this polluted air is inhaled by a person suffering from asthma, it makes that person difficult to breathe.

Excessive exposure to air pollution enhances the chances of development of asthma in kids as well as in adults, thereby affecting the lungs, immune system, and other respiratory organs.
