Answer:
The Evolutionary Theory.
Step-by-step explanation:
The evolutionary theory of government states that the first government emerged from the family. During the course of time, one family began to grow large and eventually became a clan where all the connections developed together. This clan, later on, converted into a tribe with added members and then the tribe changed into a full-fledged civilization. In civilization, the leaders are chosen to govern them and make laws that everyone agrees to obey.
The same trend can be seen in society because as a small family grows overtime and subsequently, it contributes to enlarge society.
