D. Market
Step-by-step explanation:
The economy of South Korea is best defined as a market economy, where the production and distribution of goods and services are primarily determined by supply and demand in the market. South Korea has a highly developed and diversified economy, driven by exports of electronics, automobiles, and other manufactured goods. The government plays a significant role in regulating the economy, but private enterprise is the main engine of growth. While there are elements of government intervention and regulation, the market largely determines the allocation of resources and the prices of goods and services in South Korea.
