Question

Which of the following does not cause air pollution?

• A. Increasing forest reserves
• B. Burning coal
• C. Developing housing estates
• D. Quarrying for limestone

Answer 1

The correct option is A Increasing forest reserves

Burning fossil fuels like coal causes large amount of air pollution. The construction of the housing estates results in air pollution. The quarrying of the limestone also results in the release of the particles causing air pollution. The increase in the forest reserves does not result in any kind of pollution. Rather planting more trees helps control air pollution.

Thus, the correct answer is option A.
