Question

Which statement is most accurate about the nature and types of human groups?

Answer 1

I believe the correct answer is B. Peer groups help their members define themselves.
I used the system of elimination here: A is incorrect because dyads consist of two members, and primary groups are larger than that; C is incorrect because they can be very organized and formal too; D is incorrect because a bureaucracy is a much larger group than a primary group, which is really intimate and small (but has more than two members). 

Answer 2

The answer should be B) Peer groups help their members define themselves i am pretty sure
