Explanation:
Monopoly is a structure of market where there is only one seller or producer of a specific product. Monopolistic company faces no competition in the market, and can do even unethical practices to earn profits. The most unethical practice the monopolistic company can do is the setting of product price of their own choice. Because there is no other company who is selling or producing that product in the market, the consumer's choice of selecting the product is strictly limited. Consumer has to buy the product from that seller, because he does not have any other alternative available.
