Answer:
Oligopoly.
Step-by-step explanation:
An oligopoly can be defined as a market structure comprising of a small number of firms (sellers) offering identical or similar products, wherein none can limit the significant influence of others.
Hence, it is a market structure that is distinguished by several characteristics, one of which is either similar or identical products and dominance by few firms.
The characteristics of an oligopolistic market structure are;
1. Mutual interdependence between the firms.
2. Market control by many small firms.
3. Difficult entry to new firms.
According to the concentration ratio, when a small number of companies control more than 40 percent of a market, it is called an oligopoly.
