Correct answer: A. Carbon monoxide, hydrocarbons and nitrogen oxides
- A. Carbon monoxide, hydrocarbons and nitrogen oxides
- B. Sulfur dioxide, lead and carbon dioxide
- C. Dust, smoke and asbestos fibres
- D. Chlorine, ammonia and hydrogen sulfide
Explanation
A three-way catalytic converter oxidizes carbon monoxide and unburnt hydrocarbons and reduces nitrogen oxides in suitable exhaust conditions. It is not primarily designed to remove dust or sulfur dioxide.

About Environmental Engineering
Environmental engineering examines water supply, water quality, treatment processes, wastewater collection and treatment, solid waste management, air pollution and public health protection. It covers sedimentation, coagulation, filtration, disinfection, biological treatment and disposal methods, while distinguishing drinking-water treatment from sewage treatment and BOD from COD.
