Match the pollutants given in List-$I$ with their effects given in List-$II$.

List-$I$	List-$II$
$(A)$ Phosphate fertilizers in water	$(1)$ Increases $BOD$ value of water
$(B)$ Methane in air	$(2)$ Acid rain
$(C)$ Synthetic detergents in water	$(3)$ Global warming
$(D)$ Nitrogen oxides in air	$(4)$ Eutrophication

(A-4, B-3, C-1, D-2) The correct matching is: $(A-4, B-3, C-1, D-2)$.
$(A)$ Phosphate fertilizers promote the growth of algae,which leads to eutrophication and increases the $BOD$ of water.
$(B)$ Methane is a greenhouse gas that contributes to global warming.
$(C)$ Synthetic detergents are non-biodegradable and increase the $BOD$ of water.
$(D)$ Nitrogen oxides react with water to form nitric acid,which causes acid rain.
