Answer: c. groups and group activities
Explanation:
According to the Sociologist David Orenstein, GROUPS and GROUP ACTIVITIES are the very foundation upon which social life is structured.
He believed that for humans to be social, they have to participate in groups.
That group can be small with just 2 people or really large like soldiers in a base but bottom line, humans need to be in a group to be social.
