Explanation
The correct answer is (D) All of the above.
All the options mentioned - regulations and standards, emissions charges, and transport planning - are suitable measures to control air pollution.
Regulations and standards are implemented by governments to set limits and guidelines for pollutant emissions from industries, vehicles, and other sources. These regulations help ensure that industries and vehicles meet certain emission standards, thereby reducing air pollution.
Emissions charges, also known as pollution taxes or fees, are financial measures imposed on activities that generate pollutants. By charging a fee for emitting pollutants, it provides an economic incentive for industries and individuals to reduce their emissions and adopt cleaner technologies.
Transport planning involves designing and implementing strategies to promote sustainable transportation options, such as improving public transportation systems, encouraging cycling and walking, and reducing reliance on private vehicles. This helps reduce vehicle emissions and consequently controls air pollution.
Therefore, to effectively control air pollution, a combination of regulations, emissions charges, and transport planning measures can be implemented.
