Answer

B

Explanation

When `SO_(2)` pollution in air is much higher . Sometimes `SO_(2)` mixes in the air with small particles of metals near the factories and gets oxidised into sulphur trioxide `SO_(3)`. These gases are harmful and they react with water to form sulphuric acid `(H_(2)SO_(4))` or sulphurous acid `(H_(2)SO_(3))` and come down to earth with rain water , it is called acid rain or acid precipitation.
