\nThe correct answer is D) nitrous oxide and sulphur dioxide.
\n<\/section>\n
\nAcid rain is primarily caused by atmospheric pollutants, mainly sulfur dioxide (SO\u2082) and nitrogen oxides (NOx). These gases are released into the atmosphere, primarily from the burning of fossil fuels. In the atmosphere, they react with water, oxygen, and other chemicals to form sulfuric and nitric acids. These acids then fall to the Earth’s surface through rain, snow, fog, or dry deposition. While the term “nitrous oxide” (N\u2082O) is specifically mentioned in the option, it is one of the nitrogen oxides (NOx) group, although NO and NO\u2082 from combustion are the main contributors to acid rain’s nitrogen component. However, compared to other options which list substances not responsible for acid rain (Carbon dioxide, Carbon monoxide, Ozone, Nitrogen), this option correctly identifies the two major categories of pollutants that lead to acid rain (sulfur compounds and nitrogen compounds).
\n<\/section>\n
\nSulfur dioxide emissions largely come from power plants and industrial facilities burning coal and oil. Nitrogen oxide emissions come from vehicle exhausts, power plants, and industrial combustion. Acid rain has harmful effects on ecosystems, damaging forests, lakes, buildings, and monuments.
