    The correct answer is (A) Nitrous oxide and sulfur dioxide.

    Acid rain is primarily caused by the emission of certain pollutants into the atmosphere, particularly nitrous oxide (NOx) and sulfur dioxide (SO2). These pollutants are released from various human activities, including the burning of fossil fuels in power plants, industrial processes, and vehicle emissions.

    When nitrous oxide and sulfur dioxide are released into the air, they undergo chemical reactions with water, oxygen, and other substances, forming nitric acid (HNO3) and sulfuric acid (H2SO4). These acids can then combine with water vapor in the atmosphere and fall back to the Earth’s surface as acid rain.

    Carbon dioxide (CO2), carbon monoxide (CO), and methane (CH4) are also air pollutants, but they are not directly responsible for the formation of acid rain. Carbon dioxide, in particular, is a greenhouse gas that contributes to climate change. Carbon monoxide is a toxic gas, and methane is a potent greenhouse gas. However, they do not directly cause the acidity in rainwater.
