• B. $\begin{array}{cccc}& \text{Pollutant}& \text{Source}& \text{Pollutants}\\ & & & \text{effect}\\ & N{O}_x& \text{Automobile}& \text{Photochemical}\\ & & \text{exhaust}& \text{smog}\end{array}$
• C. $\begin{array}{cccc}& \text{Pollutant}& \text{Source}& \text{Pollutants}\\ & & & \text{effect}\\ & \text{Chlorofluoro}& \text{Fossil fuel}& \text{Ozone}\\ & \text{carbons (CFCs)}& \text{burning}& \text{depletion}\end{array}$
• D. $\begin{array}{cccc}& \text{Pollutant}& \text{Source}& \text{Pollutants}\\ & & & \text{effect}\\ & \text{Methane}\left(C{H}_4\right)& \text{Agricultural}& \text{Acid deposition}\\ & & \text{farm}& \end{array}$

Answer 1

The correct option is B $\begin{array}{cccc}& \text{Pollutant}& \text{Source}& \text{Pollutants}\\ & & & \text{effect}\\ & N{O}_x& \text{Automobile}& \text{Photochemical}\\ & & \text{exhaust}& \text{smog}\end{array}$

The table given below shows some of the pollutants along with their sources and effects:

Pollutants	Sources	Pollutant effects
Sulphur dioxide	Fossil fuel burning	Air pollution
$N{O}_x$	Automobile exhaust	Photochemical smog
Chlorofluorocarbons	Refrigerants	Ozone depletion
Methane	Agricultural farm	Greenhouse effect
