The correct answer is B.free market economy.
The term "laissez faire" roughly translates to "let them do what they want." In terms of economics, this idea is the guideline for the free market economy. In a free market economy, the government does not interfer with businesses. Instead, the laws of supply and demand dictate what goods are produced and the prices are determined freely by businesses. A perfect free market economy would have no government involvement and there would be no laws dictating factors like minimum wage, benefits for employees, etc.
