D

Explanation

The gas that is considered the most dangerous pollutant to humans among the options you provided is sulfur dioxide, which is represented by sulfur (IV) oxide. Sulfur dioxide (SO2) is a colorless gas with a pungent smell and is produced by the burning of fossil fuels containing sulfur, such as coal and oil. It can have harmful effects on the respiratory system, causing irritation of the eyes, nose, and throat, and exacerbating pre-existing respiratory conditions. Additionally, sulfur dioxide can contribute to the formation of acid rain, which has further environmental consequences.
