Answer:
c. The Hawthorne effect
Explanation:
In sociology, the term Hawthorne effect refers to the tendency that people have to change their behavior because they know they are being observed (usually by a researcher). In other words, the presence of the observer changes the behavior of the persons that are being observed.
In this example, a sociologist decides to study the interaction among students in the college's computer center but when they realize they are under observation they become shy and reserved. We can observe that the students changed their behavior when they realized they were being observed. Therefore, this is an example of the Hawthorne effect.
