please select the best answer from the choices provided

○ a
○ b
○ c
○ d

Explanation:

Pollutant advisory warnings are important for health - they inform people about high pollution levels which can be harmful during exercise. Ignoring them is not a correct or safe approach. Pollutants can cause dehydration (by affecting the body's fluid balance during exercise in a polluted environment), can impair respiratory and cardiovascular systems (as pollutants can enter these systems and cause damage), and are usually concentrated around large roads and freeways (due to vehicle emissions).

Answer:

D. Pollutant advisory warnings should be ignored.
