If a sociologist points out that core nations dominate the global economy, in part by creating global interest rates and international tariffs that will inevitably favor high-income nations over low-income nations, he is a:
functionalist
dependency theorist
modernization theorist
symbolic interactionist

The correct answer is B. Dependency theorist

Explanation:

The dependency theory is an economical and social theory that was developed during the 1960s and 1970s to explain the economic situation of underdeveloped nations. According to this theory global economy is controlled by certain wealthy states that use undeveloped nation, its resources and different economic strategies such as tariffs and interest rates  to keep economy of developed or high-income nations which implies high-income nations benefit and low-income  or undeveloped nations cannot progress and its economy depends on those nations that control the global economy. Therefore, if a sociologist states core nations control the global economy and use different strategies that favor high-income nations over low-income nations he is a dependency theorist as it is in dependency theory high-income nations dominate the economy and benefit from low-income nations.
