(i) Using an incinerator
(ii) Using renewable energy
(iii) Fixing catalytic converters in vehicles

• A. Only (i)
• B. (ii) and (iii)
• C. (i) and (iii)
• D. (i), (ii) and (iii)

Answer 1

The correct option is B (ii) and (iii)

Incinerators are used to burn garbage which produces toxic ash, nitrogen oxides, carbon dioxides etc and thus, contributes to the air pollution. This method is mainly used to reduce solid wastes. Using renewable energy like solar and wind energy are the natural energy source that does not contribute to the air pollution. Catalytic converters reduce air pollution as it converts the harmful gas into the useful like it converts the carbon monoxide into the carbon dioxide which then absorbed by the plants. Thus, the correct answer is option B.
