The correct answer is option 3 - Both 1 and 2.

Explanation:

Statements 1 refers to the origin of the G-20 group. It is indeed accurate as the G-20 was initially established in 1999 as a forum for Finance Ministers and Central Bank Governors to discuss global economic and financial issues. Its mandate has since expanded to include broader issues like climate change, health, and migration.

In statement 2, it says that "Digital public infrastructure is one of India`s G-20 priorities." This is also correct. India, being one of the G-20 countries, emphasizes on digital public infrastructure as it further drives digital economy and financial inclusion.

Hence, both the statements are correct.
