The correct answer is A. Conflict theory

Explanation:

In sociology, there are different theoretical perspective to analyze politics and government. In the case of the conflict theory this deals with the inequality in society and class struggle first proposed by Karl Marx in this way according to this theoretical perspective government and thigh class that won the power are in conflict whit those that do not own the power and this is necessary for the development of society.

These ideas are supported by the Sociologist G. Willaim Domhoff in his book "Who Rules America?" as in this Domhoff explores argues the power elite or those who have money are those that own the power which means this author asserts wealth is necessary to have an influence over society and also states this situation should change which supports the idea of class struggle and shows Domhoff has a conflict theory perspective.
