The correct answer is: Water conservation and environmental sustainability.
The ‘Jal Jeevan Hariyali’ Mission is a flagship program of the Government of Bihar to ensure access to safe drinking water and improve the quality of life of the people of the state. The mission aims to achieve this by promoting water conservation, rainwater harvesting, and watershed management. It also aims to improve the quality of water through treatment and filtration. The mission has been successful in providing safe drinking water to millions of people in Bihar. It has also helped to improve the quality of life of the people by reducing waterborne diseases and improving the environment.
The other options are incorrect because they do not address the specific goals of the ‘Jal Jeevan Hariyali’ Mission. Urban housing and infrastructure is a responsibility of the state government, and agricultural development is a responsibility of the central government. Renewable energy promotion is a goal of the central government, but it is not a specific goal of the ‘Jal Jeevan Hariyali’ Mission.
