(A) Catalytic converters are used in automobiles to reduce the emission of poisonous gases like carbon monoxide and nitrogen oxides.These converters contain expensive metals acting as catalysts,specifically $Platinum$,$Palladium$,and $Rhodium$.As the exhaust passes through the catalytic converter,unburnt hydrocarbons are converted into carbon dioxide and water,carbon monoxide is converted into carbon dioxide,and nitric oxide is converted into nitrogen gas.$Selenium$ is not used as a catalyst in these converters.Therefore,the correct option is $A$.

Catalytic converters,which have expensive metals as catalysts,are fitted into automobiles for reducing emission of poisonous gases. Which of the following is $NOT$ used in them?
