According to ____ theory,interacting people always try to maximize benefits and minimize cost.

A) exchange
B) symbolic interactionism
C) norm of reciprocity
D) rational choice
E) dramaturgical analysis

The theory that suggests that interacting individuals always try to maximize benefits and minimize cost is the rational choice theory. It posits that human beings are rational beings who make decisions based on careful calculations of costs and benefits. This theory is often used in economics, political science, and sociology to explain how people make decisions in various social situations. Exchange theory is another theoretical approach used to explain social interactions, but it is more focused on the exchange of resources and social ties between individuals. Symbolic interactionism is a theoretical approach that emphasizes the importance of symbols and language in shaping social interactions. The norm of reciprocity refers to the social norm that people should return favors or benefits to those who have helped them in the past. Dramaturgical analysis explores how individuals "perform" in social situations, like actors on a stage.
