Market structures can vary according to the number of participating agents, product characteristics, and so-called barriers to entry of new companies. The study of market structures evaluates, among other factors, the size, capacity, and power that a company has to set the price of a product and its competition strategies. The various forms or market structures fundamentally depend on the characteristics:

I. Number of companies that make up the market;
II. Niche in which the company is inserted;
III. Type of product (whether companies manufacture identical or differentiated products);
IV. Whether or not there are barriers to entry for new companies in this market.
Choose the correct alternative:


a. Only II and III are correct.
b. Only I and IV are correct.
c. Only I, III, and IV are correct.
d. All alternatives are correct.
e. Only II, III, and IV are correct.
