Among the options listed, burning **coal** creates the most air pollution. Coal combustion releases a variety of harmful pollutants, including sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter (PM), and heavy metals such as mercury. These emissions contribute to smog, acid rain, and respiratory problems.
In contrast, natural gas produces fewer pollutants when burned compared to coal, making it a cleaner fossil fuel option. Electricity can vary in its pollution output depending on how it is generated (e.g., from renewable sources, coal, or natural gas), and clean fuels typically refer to renewable energy sources that have minimal or no pollution.
