Answer:
The correct answer is c. both a monopoly and a competitive firm.
Explanation:
Monopolistic competition is an imperfect type of competition in which there is a high number of sellers in the market that have a certain power to influence the price of their product.
The products offered are characterized by having some differentiation and it is precisely this differentiation that makes these companies enjoy a certain market power, have a certain voice when it comes to setting their prices and are not merely "price-acceptors", as in the case of perfect competition. Therefore, the graphic representation of monopolistic competition will be that of the right, imperfect competition.
