(A) Acid rain is a form of precipitation that is unusually acidic,meaning it possesses elevated levels of hydrogen ions (low $pH$).Acid rain is primarily caused by the emissions of sulfur dioxide $(SO_2)$ and nitrogen oxides $(NO_x)$,which react with water molecules in the atmosphere to produce acids.The chemical reactions are as follows:$2SO_2 + O_2 + 2H_2O \rightarrow 2H_2SO_4$$4NO_2 + O_2 + 2H_2O \rightarrow 4HNO_3$Among the given options,$SO_2$ is a primary contributor to acid rain.
