Final answer:
A command economic system features the government as the main economic decision-maker. Therefore, the correct option is A.
Step-by-step explanation:
In a command economic system, the government is the main economic decision-maker. This means that all decisions about what to produce, how to produce, and who receives the goods and services are made by government officials. In a command economy, resources and production decisions are planned and carried out by the government.
For example, in countries like North Korea and Cuba, the government controls and plans all economic activities. The government determines what goods and services will be produced, sets production quotas, and decides how resources will be allocated.
