B
Roots

C
Stem

D
Flowers

Solution

The correct option is A Leaves
The pollutants in the air, especially particulate matter, fly ash, dust is responsible for directly affecting the functionality of the leaves for the plants. This occurs because leaves absorb the atmospheric components of carbon dioxide (for photosynthesis) and oxygen (for respiration) through the openings in their epidermis called the stomata. The deposition of the air pollutants on the surface of the leaves blocks this diffusion ability of the stomata and the essential functions are hindered. The roots are majorly affected by the water and soil pollution because they are negatively geotropic and absorb water from the soil.
Hence, the correct answer is 'Leaves'.
