Answer:
The correct answer is A. Developing economies, like Nigeria's, are in the process of moving from an agricultural economy to an industrial economy.
Step-by-step explanation:
The main characteristic of underdeveloped economies like Nigeria is their lack of industrialization, that is, their incapacity for secondary economic production, with the consequent dependence that this generates with respect to other more industrialized countries.
These countries have predominantly primary economic production, in which they exploit their natural resources, but they do not have the capacity to transform these into manufactured products. Therefore, they are agro-export economies that in turn import industrial products. Since raw materials are cheaper than industrial products, they usually incur on trade deficit, which generates greater poverty and economic backwardness.
Therefore, developing countries, such as Nigeria, are the countries that have begun an industrialization process, with the aim of replacing their primary productivity with industrial production.
