The correct option is B Angus
The term acid rain was coined in 1872 by Robert Angus Smith. The acid rain is contains water having pH around 5.6. When the air pollutants like oxides of nitrogen and oxides of sulphur reach the troposphere, they react with the water or moisture and forms acids like nitric acid, nitrous acid or sulphuric acid. These acids then precipitate with the rain to form the acid rain. Hence, the correct answer is 'Angus'.
