Question

Pollution is controlled by

• A. Banning atomic blasts
• B. Use of electrically operated automobiles
• C. Sewage treatment
• D. All of the above

Answer 1

The correct option is D All of the above

The prevention of addition of undesirable and toxic substances will result in prevention of pollution. Banning atomic blasts would prevent soil and water pollution from the harmful release of radiations. Use of electrically operated automobiles would prevent the release of oxides of sulphur, nitrogen and carbon and so, air pollution would be prevented. Sewage treatment would remove the toxic components and would prevent water pollution.

Hence, the correct answer is 'All of the above'
