The correct answer is C) Micro-societies lacked shared characteristics among their people.
What distinguishes micro-societies from civilizations is that "Micro-societies lacked shared characteristics among their people."
Societies are formed by large groups of people that share values, traditions, history, and culture. These people have interactions on a daily basis and these interactions are the base of that society. On the other hand, in micro-societies, people do not share the characteristics that are shared in large societies. A micro-society is a small representation in a determined place of that large group of people.
