Which sociologists believe that the upper class has the most power in the power-elite?
a. the social engineering theorists
b. the behavioral theorists
c. the social-conflict theorists
d. the structural-functional theorists

The answer is C - the social conflict theorists. A cannot be correct because "social engineering" refers to influencing popular attitudes of people. B is also incorrect as the "behaviorists" deal with the behavior of people. D, "the structural-functional theorists" deal with explaining why society acts the way it does. And the correct answer is C, where "social-conflict theorists" deal with the classes where one is richer and more powerful, and the rest are not as rich nor are they powerful.
