C. Tribalism

Explanation:

There are many forms of government and "tribalism" is one which doesn't uphold a central authority. This is a primitive form of government which is no longer common these days.

In tribalism, people associate themselves into groups according to territories. So, they feel entitled to possess the resources within their territorial boundaries. They also make their own sets of rules to follow. Every tribe has its own unique kind of lifestyle. However, this form of government is not well-protected and may often face misunderstandings and sometimes wars.
