According to Goldman Sachs` review of emerging economies, the correct order of the largest economies in the world by 2050 is option 1: China-USA-India-Brazil-Mexico. Let`s analyze each option to better understand why option 1 is correct.

Option 1: China-USA-India-Brazil-Mexico

This option suggests that China will become the largest economy in the world by 2050, followed by the USA, India, Brazil, and Mexico. This aligns with the idea that China`s economy is expected to continue growing strongly, potentially surpassing the USA.

Option 2: USA-China-India-Brazil-Mexico

This option suggests that the USA will remain the largest economy in the world by 2050, followed by China, India, Brazil, and Mexico. However, this contradicts the findings of Goldman Sachs` review, which predicts China to become the largest economy.

Option 3: China-USA-Brazil-India-Mexico

This option suggests that China will be the largest economy in the world, followed by the USA, Brazil, India, and Mexico. Again, this contradicts the predicted order provided by Goldman Sachs, which places India ahead of Brazil.

Option 4: USA-M
