B) Cell phone carriers

Explanation:

An oligopoly is a store from where a market or industry is controlled by a small number of huge retailers. Oligopolies can occur from several forms of cooperation which decrease competition and reach to higher prices for customers. The auto industry is another example of an oligopoly, with the leading auto manufacturers in the United States being Ford, GMC, and Chrysler. While there are smaller cell phone service providers, the providers that tend to dominate the industry are Verizon, Sprint, AT&T, and T-Mobile.
