Final answer:
Turkey has been transitioning towards a market economy, which emphasizes private ownership and decision-making, indicative of a movement away from a government-directed approach. Hence, the correct answer is option (D).
Step-by-step explanation:
Since the 1980s, Turkey has been transitioning from a government-directed economy towards one with more private ownership, signaling a move toward a market economy. This shift means that the economic system is increasingly allowing private individuals and firms to make decisions about what to produce, how to produce it, and for whom to produce it, with less government intervention.
Most economies in the world today, including that of the United States, Europe, and Latin America, are considered mixed economies because they blend elements from both market and command systems, although they may lean more towards one end of the spectrum.
