Answer:
b. symbolic interactionism
Step-by-step explanation:
In sociology and social psychology, the theory of symbolic interactionism focuses on the relationships between individuals who are part of a society. In this theory, one important thing is language and the whole concept of how we communicate with one another, in other words it states that it is through our verbal and non verbal language (also attitudes) that we make sense of our world and this language also shapes our own behavior at the same time.
In this example we have the statement "Gender is socially constructed and maintained in our everyday lives. Gender is something we 'do' on a daily basis. We can see that this statement refers to patterns of behavior that take place among individuals who are part of a society, it also mentions how gender is socially constructed and thus, we communicate it with our verbal and non-verbal language in our day-to-day lives. Thus, this statement most likely comes from the symbolic interactionism perspective.
