India's National Action Plan on Climate Change (NAPCC) was launched in June 2008 to outline the country's strategy for both mitigating and adapting to climate change. It is organised around eight national missions, each targeting a specific dimension of the climate challenge. The correct choice, the National Solar Mission (also known as the Jawaharlal Nehru National Solar Mission), is one of these eight and focuses on greatly expanding grid-connected and off-grid solar power to reduce dependence on fossil fuels.

The eight missions under the NAPCC are:

1. National Solar Mission — promoting solar energy.
2. National Mission for Enhanced Energy Efficiency.
3. National Mission on Sustainable Habitat.
4. National Water Mission.
5. National Mission for Sustaining the Himalayan Ecosystem.
6. National Mission for a Green India.
7. National Mission for Sustainable Agriculture.
8. National Mission on Strategic Knowledge for Climate Change.

The distractors are all genuine government initiatives, but none is a NAPCC mission:

• The National Nutrition Mission (POSHAN Abhiyaan) is a health and child-nutrition programme.
• The National Rural Livelihood Mission is a poverty-alleviation and self-employment programme.
• The National Highway Development Project is a road-infrastructure programme.

Since these belong to the social-welfare and infrastructure domains rather than the climate-change framework, only the solar energy mission fits the question.
