The correct answer is A) managing disputes over distribution.
An organized government would most likely support the existence of food surpluses by managing disputes over distribution.
Food surpluses mean that consumers would have more food for consumption. According to the law of supply and demand, when there is a surplus or and excedent of one product, it tends to be cheaper because there is more than people needed. The opposite would be a shortage when there is a limited number of this product in the market and the price rises because many people would demand it.
