Correct Answer - Option 2 : D

The correct answer is Lead.

  • The exhaust manifold is the first important element.
  • The catalyst is another element of the exhaust system.
  • It uses chemical reactions to reduce harmful gases by converting them into carbon dioxide, water vapor, and pure nitrogen.
  • The toxic elements present in automobile exhausts are carbon monoxide (CO), nitrogen oxides, and particulate matter (fine carbon particles).
  • The toxic elements lead to various respiratory diseases, cancer, and allergic reactions in humans and animals.
  • Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, or coal.
