Question

Which of the following would not be effective in reducing air pollution?

• A. Solar energy
• B. Use of CNG
• C. Use of electric cars

Answer 1

The correct option is D All of these

Extensive use of fossil fuel can directly result in the increase of carbon dioxide and other pollutants in the air.

Air pollution can be reduced by the following methods:

(i) Use of electric cars - It runs on electricity and does not emit smoke, therefore creates no pollution.

(ii) Using solar energy - It is a non-polluting and non-depleting source of energy.

(iii) Use of CNG as a fuel - It is cleaner than petrol and diesel.
