Answer:
Oligopoly.
Step-by-step explanation:
The market structure in which the behavior of any given firm depends on the behavior of the other firms in the industry is oligopoly.
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.
