Which pollutant is commonly linked to acid rain produced by fossil fuel combustion?

• A. Sulfur dioxide
• B. Neon
• C. Argon
• D. Helium

Answer: (A)

Sulfur dioxide is the pollutant most commonly linked to acid rain from fossil fuel use. When fuels like coal and oil that contain sulfur are burned, sulfur compounds are released as SO2. In the atmosphere, SO2 can be transformed into sulfuric acid through chemical reactions that involve oxygen and water. This sulfuric acid precipitates with rain, fog, or snow, lowering the acidity of the environment and causing damage to forests, lakes, and man-made structures. The other options don’t fit because neon, argon, and helium are inert noble gases that don’t react to form acids and aren’t produced in significant pollutant quantities by fossil fuel combustion, so they aren’t associated with acid rain.
