Which device in vehicles converts poisonous gases due to burning of petrol or diesel into harmless gases?

Correct option is B

The correct answer is (b) Catalytic converter.
· A catalytic converter is a device used in vehicles to convert harmful gases produced by the combustion of petrol or diesel, such as carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbons, into less harmful gases like carbon dioxide (CO₂), nitrogen (N₂), and water (H₂O).
· It plays a crucial role in reducing vehicle emissions and improving air quality.
Information Booster:
· Radiator: Helps in cooling the engine, not related to emissions.
· Carburettor: Mixes air and fuel for internal combustion in older engines, not used in modern vehicles with fuel injectors.
· Inverter: Converts DC to AC electricity, not related to exhaust emissions.
