Which pollutant is commonly released from sulfur in fuels and contributes to acid rain?

Explanation:
When fuels contain sulfur, burning them releases sulfur dioxide into the atmosphere. This gas reacts with water and oxygen in the air to form sulfuric acid and related sulfate particles, which fall as acid rain. That direct link—sulfur in fuel becoming sulfur dioxide and then acid rain—is why this pollutant is the correct choice. The other pollutants aren’t released specifically because of sulfur in fuels: carbon monoxide comes from incomplete combustion, ozone forms later in the atmosphere from sunlight reacting with other pollutants, and nitrogen oxides come from nitrogen in air and fuels, not sulfur content.
