Final answer:
Option C is NOT true. The BRICS countries do not contribute more than 50% of global GDP on a PPP basis.
Step-by-step explanation:
Option C is NOT true of the emerging economies of Brazil, Russia, India, and South Africa (BRICS). These countries do not contribute more than 50% of global GDP on a PPP (purchasing power parity) basis. While the BRICS countries are considered emerging economies and have shown significant economic growth, their combined contribution to global GDP is less than 50% on a PPP basis.
For example, in 2020, according to the International Monetary Fund (IMF), the BRICS countries accounted for around 34% of global GDP on a PPP basis. This shows that they are important players in the global economy, but they do not contribute more than 50%.
Therefore, option C is the correct answer.
