Consider the following statements:
1. The International Solar Alliance was launched at the United Nations Climate Change Conference in 2015.
2. The Alliance includes all the member countries of the United Nations.
Which of the statements given above is/are correct?

Correct Option: (a) 1 only

The International Solar Alliance (ISA) was jointly launched by India and France in 2015 at the UN Climate Change Conference (COP21) in Paris, making statement 1 correct. It does not include all UN member countries as membership was initially restricted to countries lying fully or partially between the Tropics of Cancer and Capricorn (though later amended to all UN members, at the inception and relevant exam time, statement 2 was incorrect).
