Answer: B. Nomadic herders
Step-by-step explanation:
Shepherds who move from place to place in order to feed their livestock are known as nomadic herders because nomadic is used to refer to people who move around and do not settle in one place.
Nomadic herders can sometimes come into conflict with the people who own the land that the nomads migrate to and this has created some very deadly conflicts in recent years in West Africa.
