Answer: B) Command</h3>
For instance, the government sets prices of all goods in a command economy and they also set the production level (ie how much of a certain item to produce).

An example of a mixed economy is the United States where free market forces determine prices though there are government regulations set up to ensure the economy doesn't go south, and to ensure fair trade practices are followed.
