Answer:
The correct answer is D. Mixed economy.
Step-by-step explanation:
A mixed economy is a form of economic system in which the state strongly intervenes in private economic processes. However, it is not a central administration economy, as there is always a market economy in the background.
Mixed economies are characterized, among other things, by a high degree of interlinking of business and politics, a large amount of state participation in publicly significant companies, an economically active bureaucracy, strong regulation and strong state intervention in the economy, for example through the specifications of economic, competition, research and labor market policy.
