Explanation:

G-7 is a bloc of industrialized democracies i.e. France, Germany, Italy, the United Kingdom, Japan, the United States, and Canada.

• It's an intergovernmental organisation that was formed in 1975. The bloc meets annually to discuss issues of common interest like global economic governance, international security and energy policy.
• The G7 does not have a formal constitution or a fixed headquarters. The decisions taken by leaders during annual summits are non-binding.
• Apart from India, Australia and South Korea were also invited to participate in the proceedings of the summit as “guest countries”. (India is not part of G7 grouping). 
• At the 47th G7 summit 2021 the G7 signed the Carbis Bay Declaration. It is aimed at preventing future pandemics. 
• The G7 also pledged over 1 billion coronavirus vaccine doses for poorer nations with half of that coming from the United States and 100 million from Britain.

Hence only statement 2nd is correct.
