Answer:
Government
Step-by-step explanation:
The statement is asking about entities that have their own government and their own way of doing things. This means that these entities are autonomous and have the power to make their own decisions and implement their own rules, without being controlled by another entity.
Examples of entities that fit this description are cities, countries, or autonomous territories.
Option B (Cities) is most likely the answer to the statement, as cities are relatively small administrative divisions that have their own local government and unique cultural, economic, and social systems.
