Question

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

• A. Use of fuels
• B. Use of public transport
• C. Walking
• D. Use of cycle

Answer 1

The correct option is A Use of fuels

Extensive use of fuels like petrol, diesel, wood, etc., can directly emit carbon dioxide and other harmful gases in the air. Use of public transport produces less pollution than travelling in individual vehicles. The advantage of walking or using cycle is it does not use any fuels which cause air pollution.
