Answer: Option D

An oligopolistic industry is characterized by a few organizations. The products that are produced in the industry are homogeneous or differentiated. The organizations that exist in the markets are interdependent. This means that a decision one firm makes must consider the effect it will have on the other players in the industry. The automobile industry is an example of an oligopoly. If there are no government regulations, it is possible that oligopolistic organizations may collude to set prices as monopolists do.
