Answer:
Option C.
Explanation:
Band, is the right answer.
A band is generally a small nomadic group which is connected by the ties of family and is politically independent. By nomadic group, we mean those people who move from one area to another in search of food accordingly, this term generally signifies the hunter-gatherers.
Since the hunter-gatherers live in small groups and moving around is their way of living, such bands used to have little or no formal leadership. Accordingly, decisions such as when to move and when to stay are made by group consensus.
