Answer:
d. Producers, who earn a higher price on the sale of each unit and also sell more units, thereby unambiguously earning higher revenues
Step-by-step explanation:
A government price support program is when the government impose a price limit on a product to control the price of the product i.e price floor, and also the purchase of any surplus. The price floor and the purchase of any surplus for the product encourages the producers to produce more of the product.
Since price floor must be higher than the equilibrium price for it to be effective, the producers of the agricultural product earn more by selling in units and also earn more for selling any surplus to the government.
