Answer:
The answer is command economy.
Step-by-step explanation:
The example given in the question describes a command economy. In a command economy, the produced goods' price is not adjusted according to the supply and demand curve or by the companies that do the production. It is instead adjusted by the government, so is the rate of production, and what the product will be. This situation checks all those boxes. The government is deciding that the product will be cars, how many will be produced and what price they are going to be sold at.
So the answer is A, command economy.
I hope this answer helps.
