The correct answer is B) tenant farmers.
The people that paid rent to a landowner to raise crops and lived on the landowner's land, which sometimes led to them being exploited were called tenant farmers.
Tenant farming was an agriculture system in the United States, in the years after the Civil War. Farmers rented a portion of land the owner and worked the land. They could keep some money after paying the rent to the landlord or sometimes owners allowed farmers a small portion of the crops. Farmers were poor people that needed to work to feed their families and tenant farming was an option, not the best one because most of the time the owner of the land exploited the farmer.
