The correct answer is: "a mixed economy".
In a command economy, the three fundamental questions of economics: what to produce, how to do it and for whom, are answered by the goverment. The public sector controls the whole economy and all the property is public.
The other extreme case is the market economy, where the interactions of the private economic agents (households and firms) define the outcomes that answer the three fundamental questions. There is no goverment intervention and no public properties at all.
If in an economic system the goverment controls almost everything but private property is still allowed, it cannot be a command economy, as private agents get some degree of power and ability to decide (just over the property, but still this power is more than nothing). <u>Every system, located between the extreme cases defined above is called a mixed economy. </u>
