Answer:
The correct answer is oligopoly.
Explanation:
An oligopoly is a market structure in which there are a few firms that are dominant in the market. These firms may produce identical or differentiated products.
Because of a few firms in the market, the firms are interdependent on each other. Market decisions of a firm affect its rivals.
That is why before making their own decisions, the firms have to consider the reaction of their rivals.
