1. Around 85% of the global GDP
2. About 50% of the global trade
3. About two-thirds of the world population
Which of the above statistics is/are correct?

Correct option is B

The G20 is an international forum that includes 19 countries and the European Union, focusing on major global economic issues. The G20 countries represent:

Around 85% of global GDP—This is correct. The G20 nations collectively account for about 85% of the world’s total economic output.
About 75% of global trade, not 50%, which makes this statement incorrect in the given form. G20 countries dominate global trade, but the percentage mentioned in the question is lower than the actual value.
About two-thirds of the world population—This is correct. The G20 countries represent approximately two-thirds (or around 66%) of the global population, largely due to the inclusion of highly populous nations like China and India.
