Question

What makes a state unique relative to other organizations within its territory

Answer 1

The answer is b. The state claims ultimate rule-making authority

When other organizations make a certain rule, only all the members of the organization are obligated to follow it.
When the states make the rule, it would override all organizations' rule that operates within the state's border.
If the rules of the organizations contradict the rules of the states, the citizens are obligated to obey the states rules.
