Solution

The correct option is B decreases
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of Sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.
