A. Coal and B. Petroleum both produce polluting substances when burned.
Coal is particularly known for producing a variety of pollutants, including sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter, and heavy metals.
Petroleum also emits pollutants, including carbon dioxide (CO2), nitrogen oxides, and volatile organic compounds (VOCs) when burned.
Natural gas (C) is generally considered the cleanest of the three fossil fuels, producing lower emissions of carbon dioxide and other pollutants compared to coal and petroleum. However, it still emits CO2 and methane (a potent greenhouse gas) when burned.
So, coal and petroleum are the primary sources of polluting substances when burned.
