Answer :
"B) Citizens have economic freedoms with some government regulation" is the best reason for why economists describe the US economy as a mixed-market economy.
The correct answer is B) Citizens have economic freedoms with some government regulation.
A mixed-market economy is one in which there is government regulation but at the same time citizens have the ability to make their own decisions. In the United States, the US has this type of economy. The US federal government has some regulations created by the Food and Drug Administration to ensure that the food sold to the American public is safe. At the same time, citizens have the ability to spend their money at whatever businesses they want and have the chance to buy whatever they want.
