A market characterized by many firms offering identical products is known as:

In a market characterized by many firms offering identical products, the correct answer is perfect competition. This market structure is characterized by a large number of sellers who provide products that are indistinguishable from one another, meaning there is no differentiation. Because the products are identical, consumers choose based solely on price, and firms are price takers, unable to set prices above the market equilibrium.

In perfect competition, factors such as ease of entry and exit for firms, perfect information for both producers and consumers, and the homogeneity of products contribute to a highly competitive environment. This results in firms earning normal profits in the long run, as any above-normal profits would attract new entrants, increasing supply and driving down prices.

Monopolistic competition, while it involves many firms, typically has product differentiation, meaning firms offer similar yet distinct products. Oligopoly involves a few large firms dominating the market, and a monopoly refers to a single firm controlling the entire market. These market structures do not fulfill the conditions of having identical products provided by many firms, which is why they are not the correct answer.
