Correct answer
CA-IV, B-III, C-II, D-I

Step-by-step explanation

Nitogen oxides are produced by various natural and human activities, including combustion processes, industrial emissions, and vehicle exhaust. These are responsible for acid rains. 

Methane (CH4) is a potent greenhouse gas that contributes to global warming. While carbon dioxide (CO2) is the most well-known greenhouse gas. Carbon dioxide present in air, react with the rain water to form carbonic acid.

The excessive use or runoff of phosphate fertilizers into bodies of water can contribute to eutrophication.

A Nitrogen oxides in air IV Acid rain
B Methane in air III Global warming
C Carbon dioxide II pH of rain water becomes 5.6
D Phosphate fertilisers in water I Eutrophication

∴ A-IV; B-III; C-II; D-I
