Match the columns :

Column - $I$	Column - $II$
$(1)$ Nitrous oxide	$(a)$ Secondary pollutant from car exhaust.
$(2)$ Chlorofluorocarbons	$(b)$ Combustion of fossil fuels,wood etc.
$(3)$ Methane	$(c)$ Denitrification
$(4)$ Ozone	$(d)$ Refrigerators,aerosols,sprays
$(5)$ Carbon dioxide	$(e)$ Cattle,rice fields,toilets

(C) The correct matching is as follows:
$(1)$ Nitrous oxide is produced by the process of denitrification in soil,so $(1-c)$.
$(2)$ Chlorofluorocarbons (CFCs) are primarily used in refrigerators,aerosols,and sprays,so $(2-d)$.
$(3)$ Methane is released from sources like cattle,rice fields,and anaerobic decomposition in toilets,so $(3-e)$.
$(4)$ Ozone in the troposphere is a secondary pollutant formed from car exhaust emissions,so $(4-a)$.
$(5)$ Carbon dioxide is released by the combustion of fossil fuels and wood,so $(5-b)$.
Therefore,the correct sequence is $(1-c, 2-d, 3-e, 4-a, 5-b)$.
