Answer:
Correct answer: A person with a Twitter account and 2,000 followers
Step-by-step explanation:
Primary group is a sociological classification whereby there is a face-to-face interaction between member of the group together. This primary group is the center of all social interactions. Also, it represent the foundation for the common purpose and life of the group.
A person with a Twitter account and 2,000 followers is not an example of primary group because, their interaction was never face-to-face. Rather, it was virtual and most times, the members might not be online.
