The correct option is C Nomadic community
A nomad ((in Latin) "people without fixed habitation") is a member of a community of people without fixed habitation who regularly move to and from the same areas, including nomadic hunter-gatherers, pastoral nomads (owning livestock), and tinker or trader nomads. A nomad is a person with no settled home, moving from place to place as a way of obtaining food, finding pasture for livestock, or otherwise making a living. Community does not have any economic security and earn money through rag picking, bucket repairing, fishing, hunting, selling small fancy products, etc. Nomadic peoples traditionally travel by animal or canoe or on foot.
