Which of the following pollutants is produced by burning fossil fuels?

Sulfur dioxide is indeed one of the primary pollutants produced by the combustion of fossil fuels, particularly when coal and oil are burned. When these fuels are burned, the sulfur contained within them reacts with oxygen to form sulfur dioxide. This gas is significant because it contributes to air pollution and can lead to the formation of acid rain, which has harmful effects on the environment, including damage to vegetation, soil, and water bodies.

While other pollutants listed, such as nitrogen oxides and carbon monoxide, are also produced from burning fossil fuels, sulfur dioxide is specifically linked to the combustion of sulfur-containing fuels. Methane, on the other hand, is predominantly a product of natural gas usage, agricultural processes, and is not released in notable amounts from the burning of fossil fuels. Therefore, sulfur dioxide stands out as a key pollutant specifically related to the burning of fossil fuels.
