The factor that has a negative impact on Africa's economics among the options provided is the lack of quality healthcare in Africa.
A lack of quality healthcare can lead to a range of economic issues, including decreased workforce productivity, increased healthcare costs for individuals and governments, and decreased overall quality of life. Poor health outcomes can hinder economic growth and development by limiting the ability of individuals to work and contribute to the economy.
In contrast, the presence of non-governmental organizations, collaboration among organizations, and monetary investment by foreign nations generally aim to support and improve economic conditions and development in Africa, although the effectiveness and outcomes of these efforts can vary.
