## Step 1The problem is asking us to identify the primary air pollutant produced from burning coal. The options provided are Carbon monoxide, CFCs (chlorofluorocarbons), PCBs (polychlorinated biphenyls), Ozone, and Sulfuric acid.## Step 2We need to understand what each of these pollutants is and where they come from. ## Step 3Carbon monoxide is a colorless, odorless, and tasteless gas that is produced by the incomplete combustion of carbon-containing materials, such as coal. ## Step 4CFCs (chlorofluorocarbons) are not produced by burning coal. They are synthetic compounds that were once widely used in refrigeration and aerosol sprays. ## Step 5PCBs (polychlorinated biphenyls) are not produced by burning coal. They are a type of industrial chemical that was used in electrical equipment and other applications. ## Step 6Ozone is not a primary air pollutant produced by burning coal. It is a secondary pollutant that forms in the atmosphere when nitrogen oxides and volatile organic compounds react in sunlight. ## Step 7Sulfuric acid is not a primary air pollutant produced by burning coal. It is a secondary pollutant that forms in the atmosphere when sulfur dioxide reacts with water vapor. ## Step 8Based on the above information, the primary air pollutant produced from burning coal is Carbon monoxide.
