The correct answer is option 2, Home Affairs. The National Disaster Management Authority (NDMA) is a government body that is responsible for planning, coordinating, and implementing measures to minimize the impact of disasters in India. It functions under the Ministry of Home Affairs.

Option 1, Environment, Forest and Climate Change, is incorrect because this ministry primarily focuses on environmental conservation and climate change-related issues, rather than disaster management.

Option 3, Commerce and Industry, is incorrect because this ministry primarily deals with matters related to trade, industry, and economic development, rather than disaster management.

Option 4, Finance, is incorrect because this ministry primarily deals with matters related to public finance, taxation, and economic policies, rather than disaster management.

It is important to note that the Ministry of Home Affairs plays a crucial role in coordinating various aspects of disaster management, including response, recovery, and mitigating future risks. Thus, the correct answer is option 2, Home Affairs.
