The correct answer is: C. Monopoly
Price discrimination is a pricing strategy in which a company charges different prices for the same product or service to different groups of customers. This can be done based on factors such as customer location, customer income, or the time of day.
Price discrimination can help a company increase profits by allowing it to charge a higher price to customers who are willing and able to pay more. For example, a company might charge a higher price for tickets to a concert to people who want to sit in the front row than to people who are willing to sit in the back row.
Price discrimination is not possible in a perfectly competitive market, because in a perfectly competitive market, there are many companies selling the same product or service. This means that companies cannot charge different prices to different customers, because customers would simply buy the product from the company that is charging the lowest price.
Price discrimination is also not possible in a monopolistically competitive market, because in a monopolistically competitive market, there are many companies selling similar products or services. This means that companies cannot charge different prices to different customers, because customers would simply buy the product from the company that is offering the best deal.
Price discrimination is possible in a monopoly market, because in a monopoly market, there is only one company selling the product or service. This means that the company can charge different prices to different customers, because customers have no other choice but to buy the product from the company.
Oligopoly is a market structure in which there are a few large companies selling the same product or service. In an oligopoly, companies can sometimes engage in price discrimination, but it is more difficult than in a monopoly market. This is because companies in an oligopoly are afraid that if they charge different prices to different customers, their competitors will lower their prices and steal their customers.
In conclusion, price discrimination is a pricing strategy that can help a company increase profits. It is possible in a monopoly market, but it is more difficult in an oligopoly market.
