The option that has negatively affected Africa's economies is:
The lack of quality health care in Africa.
Poor health care systems can lead to a decline in workforce productivity, increased healthcare costs, and greater vulnerability to diseases, ultimately negatively impacting economic growth and stability.
The other options, such as the presence of nongovernmental organizations, collaboration among organizations like the African Union, and monetary investment by foreign nations, typically have positive effects, although they can have complex repercussions depending on the context.
