(B) Acid rain is primarily caused by the emission of sulfur dioxide $(SO_2)$ and nitrogen oxides $(NO_x)$.When these gases are released into the atmosphere,they react with water vapor,oxygen,and other chemicals to form sulfuric acid $(H_2SO_4)$ and nitric acid $(HNO_3)$.These acids then fall to the ground with rain,causing environmental damage.Among the given options,sulfur dioxide $(SO_2)$ is the primary gas responsible for acid rain.
