Answer:
(iii) maximize profit.
Explanation:
(i) Selling as much as possible is not always a viable business model, regardless of how much it sells, a firm might not perform well if it is selling its products at a low profit margin or even at a loss.
(ii) Setting an extremely high price for a product may decrease demand and open up opportunities for competitors to enter the market selling at a lower price; an optimal equilibrium price is preferable to the highest possible price.
(iii) According to economists, this should be the main goal of a firm. Be it by reducing costs or increasing revenue, maximizing profits should be the aim of a business.
