A) I & II
B) Only II
C) II & III
D) All the above
Correct Answer: C
Solution :
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). The term "acid rain" was coined in 1872 by Kobert Angus Smith, after a link was established between sulfur dioxide emissions from the burning of coal in Manchester and acidification of nearby rainfall. Rainfall with pH less than 5.6 is called Acid rain.You need to login to perform this action.
