Correct Answer: Control air pollution in cities

Solution : The correct answer is (D) Control air pollution in cities.

The "National Clean Air Programme" (NCAP) in India is a comprehensive action plan launched by the Government of India in 2019 with the objective of tackling air pollution in the country. The program focuses on addressing air pollution issues in 102 non-attainment cities, which are cities that do not meet the air quality standards set by the Central Pollution Control Board.

The key aim of the NCAP is to achieve a significant reduction in air pollution levels in these cities by implementing various measures. These measures include strengthening the monitoring and assessment of air quality, promoting public participation and awareness, improving emission inventories, adopting technological interventions for controlling air pollution, and enhancing the capacity of pollution control agencies.

By implementing the NCAP, the government aims to achieve a 20-30 % reduction in air pollution levels in these cities by 2024 compared to the 2017 baseline. The program takes a multi-sectoral approach and involves collaboration between central, state, and local governments, as well as other stakeholders, to address the sources of air pollution and improve air quality in urban areas.
