The correct answer is A. That previously low-income nations such as China have successfully developed their economies and can no longer be classified as dependent on core nations
Step-by-step explanation:
The Dependency theory is a theory on sociology that states the global inequality can be explained due to the dependence or peripheral nations on core or high-income nations that exploit the resources of dependent nations to preserve a strong economy while peripheral nations remain underdeveloped and unable to develop economies. Although this theory is supported by many, it is also criticized especially as it does not recognize some of the peripheral or low-income nations had ended with the dependency relationship and develop their economy successfully, this it the case of China and other countries that went from the periphery to core nations. Therefore, one flaw in dependency theory is the unwillingness to recognize that previously low-income nations such as China have successfully developed their economies and can no longer be classified as dependent on core nations.
