Question 22

Explanation

The correct answer is: There are many buyers and sellers of the same product or service, and the market information is symmetrical. These are two of the key features of a perfect competition, according to the dictionary definition1 and the web search results. In a perfect competition, there are many firms that offer a homogeneous product, meaning that the product is identical or very similar among different sellers. This implies that no seller has a competitive advantage or market power over others, and they are all price takers, meaning that they cannot influence the market price of their product. The market information is symmetrical, meaning that all buyers and sellers have full and equal knowledge about the product and the prices charged by each firm. This ensures that there is no information asymmetry or market failure in a perfect competition. Therefore, these two features are essential for a perfect competition to exist.

The other options are not features of a perfect competition, but rather of other market structures. For example, having only one seller of the product or service is a feature of a monopoly, where a single firm dominates the market and can set any price it wants. Having a unique and differentiated product or service among different sellers is a feature of a monopolistic competition, where there are many firms that offer slightly different products that appeal to different consumer preferences. Having barriers to entry and exit for new sellers is a feature of an oligopoly, where there are few firms that dominate the market and can prevent new entrants from competing with them. These market structures are all examples of imperfect competition, which deviate from the ideal model of perfect competition.
