ANSWER
An electrostatic precipitator removes particulate matter by imposing a negative charge on them. Then they are separated electrostatically.
Catalytic converters convert unburnt hydrocarbons into CO2CO2 and water. They are used in automobiles.
Peroxyacyl nitrates (PANs) is a secondary pollutant formed by reaction of oxides of nitrogen and unsaturated hydrocarbons.
DDT is a non-biodegradable pollutant.
All the given statements in the question are correct,
So, the correct option is 'None of these'.
