A cartel differs from a monopoly in that B) businesses making the same product agree to limit production. A cartel is an agreement between producers of goods, usually primary products like oil or natural gas, who work together to set a price at an agreed upon price that is a distortion above of what the market's equilibrium price would be for the good without the cartel's intervention.
A cartel is a collaboration among businesses that produce the same product to limit production and raise prices. In contrast, a monopoly is when one company has complete control over a market. Therefore, the correct answer is B.
