The correct answer is: B. Monopoly
A monopoly is a market structure in which there is only one seller of a good or service. The monopolist has a great deal of market power, and can therefore charge a high price for its product. This can lead to a number of problems, such as inefficiency and a lack of innovation.
A monopsony is a market structure in which there is only one buyer of a good or service. The monopsonist has a great deal of market power, and can therefore pay a low price for the good or service. This can lead to a number of problems, such as inefficiency and a lack of innovation.
A bilateral monopoly is a market structure in which there is only one buyer and only one seller of a good or service. The buyer and seller have a great deal of market power, and can therefore negotiate a price that is favorable to them. This can lead to a number of problems, such as inefficiency and a lack of innovation.
