Answer:
a. conflict perspective.
Explanation:
The conflict perspective is one of the main research traditions in sociology, including several theoretical approaches. Marxism, feminism, various Weberian perspectives, and many others — all these strands employ some version of the theory of conflict. Conflict theories investigate the importance of these social structures in society, which produce chronic tensions and rivalries that eventually erupt into violence. Some theories, such as Marxism, place structured class conflicts at the center of society as the dynamics that drive social change. It is worth remembering Simmel's argument here, namely that while social classes are in conflict, they are also immersed in relations of mutual dependence. Under capitalism, workers depend on the capitalists who offer them jobs and the income necessary for their survival. Capitalists, on the other hand, need workers to be able to provide the products and services that earn them profits.
