The options available are:
A. Import oriented economy
B. Lack of infrastructure
C. Problems with immigration
D. Civil wars
Answer:
B. Lack of infrastructure
D. Civil wars
Explanation:
Lack of infrastructure in Africa is one of the major problem that prevents Africa from being able to fully utilize its resources, this because there is not massive and robust factory infrastructures that can process many of its natural resources into refined and final resources. For example, in terms of crude oil and natural gas, there is no substantial refinery in Africa to process it to final products.
Civil wars is also one of the bane that is preventing the Africa from harnessing its resources, as civil wars leads to vandalization of the little infrastructures that is present there, it also affects the government policies, destroys human lives or resources, and scare away both local and foreign investors.
Immigration problems has nothing to do with the utilization of resources, as many Nldeveloped Nations faced the same problems, such as USA with the influx of Mexicans trooping into the country for greener pastures.
It is not import oriented economy either, because, import oriented economy is also one of the byproducts of lack of infrastructure.
