Let's analyze the question asking about who launched the International Solar Alliance.

The International Solar Alliance (ISA) is a treaty-based intergovernmental organization that works to promote solar energy. It was conceived as a joint effort to mobilize resources and provide access to solar energy in member countries.

The launch of the International Solar Alliance was a significant event in global efforts to combat climate change and promote renewable energy.

Looking at the options:

• Narendra Modi: The Prime Minister of India.
