The correct answer is citizens can change jobs relatively easily.
A market economy is one in which citizens have significant freedom of choice. This is due to a lack of government intervention within an economy. In a market economy the products businesses make, the decisions on what to purchase, and how to use resources are left all up to the individual. This is why the first statement is correct, as all of the other options are part of a command economy (one in which the government makes decisions for the people).
