To assess human capital generally, we can consider both GDP per capita and literacy rate as indicators. Here's the summary from the table:
- Egypt: GDP per capita $3,514.49, Literacy Rate 73.8%
- Sudan: GDP per capita $2,415.04, Literacy Rate 75.9%
- Nigeria: GDP per capita $2,177.99, Literacy Rate 59.6%
- South Africa: GDP per capita $5,273.59, Literacy Rate 94.3%
Looking at both GDP per capita and literacy rates, Nigeria stands out with the lowest values in both categories:
- GDP per capita: $2,177.99 (lowest)
- Literacy Rate: 59.6% (lowest)
Thus, Nigeria has the lowest human capital among the countries listed.
The answer is B. Nigeria.
