least developed country theory
dependency theory
labor theory
sustainable development theory

The correct answer is C) a dependency theory.

Wallerstein's Theory is an example of a dependency theory.

Immanuel Wallerstein is the creator of the World Systems Theory that establishes that rich and dominant nations exploit poor and underdeveloped countries.

This theory is an example of the Dependence Theory.

This theory states that there are underdeveloped countries that are exploited by developed and rich nations. The wealthy countries exploit the raw materials and natural resources of those poor countries.

Underdeveloped nations have plenty of resources but never have had the industries that transform those raw materials into goods. Why? because they are poor and don't have money to create industries.

On the other hand, wealthy countries are very rich and although they do not have raw materials, they have the money to develop industries that transform those raw materials into goods.
