Answer:
C. Development is low or average throughout the region.
Step-by-step explanation:
According to the statistic by the Worldbank, all of the bottom ten countries in term of economic development are located in sub-Saharan Africa.
These region had a really harsh climate. Making it almost impossible for agricultural sector to fully thrive. As a result, food commodities are really hard to found within the countries that located in this region and a lot of rebel groups started to arise due to inability of the government to provide security for its people. On top of that, this region made up around 90% of HIV-related cases in this world.
The combination of these factors made a lot of young generations in Africa economically unproductive and caused the low level of economic development.
