Answer:
Hello. You did not put the answer options, but I can help you by saying that the factors that led to the development of plantation agriculture in the South were the climate, the existence of plains and the fertile soil.
Step-by-step explanation:
Most of the southern United States has soils with high fertility and with low prevalence of low plains and lands. In addition, the south has hot summers and dwarf winters, which means that plantation agriculture is favored to a great extent. This allowed the USA to become a strong agricultural power, in addition to allowing the southern states to be responsible for the consumption of food in the country.
In this case, in addition to livestock, the southern United States had a good establishment of crops such as wheat, barley and rye.
