Which acid mostly contributes to acid rains?

hydrochloric acid
sulfuric acid
nitric acid
citric acid
The most im­por­tant gas which leads to acid­i­fi­ca­tion is sulfur dioxide, coming from fossil fuel com­bus­tion and industry (and, in lesser amounts, from vol­ca­noes and wild­fires). In recent years, emis­sions of nitrogen oxides which are oxidized to form nitric acid are of in­creas­ing im­por­tance due to stricter controls on emis­sions of sulfur con­tain­ing com­pound­s.
