Answer:
The correct answer is: oligopoly.
Step-by-step explanation:
A market structure where there are only a few firms is called an oligopoly market. These firms can be producing either identical products or differentiated products.
Because of few firms, there is a high degree of competition in the market. The firms are price makers and face a downward sloping curve.
There is interdependence in the market such that the economic decisions of a firm affects the price, profits and output level of its rivals. So the firms have to consider the reaction of its rivals before making an economic decision.
