Final answer:
Real GDP per person fell by about 38% from 1991 to 2011 in Zimbabwe, making option C) Zimbabwe the correct answer. India and Singapore experienced economic growth in this period, which eliminates options A and B.
Step-by-step explanation:
In Zimbabwe, the real GDP per person fell by about 38% from 1991 to 2011. Therefore, the correct answer is C) Zimbabwe. This period was marked by severe economic decline, hyperinflation, and political turmoil, leading to a significant contraction in economic activity and a devastating impact on the country's GDP per capita.
Conversely, countries like India and Singapore experienced economic growth during this period. India, in particular, showed promising signs of economic expansion, with its GDP per capita growing about 4% per year during the 1990s, and climbing toward 7% to 8% per year in the 2000s. Therefore, options A) India and B) Singapore are incorrect.
