Concept:Economic agents are the main decision-makers in an economy, such as those who produce, consume, and regulate economic activities.
Explanation:The three basic economic agents are households, firms, and government.
Households supply labour and consume goods and services.
Firms produce goods and services using available resources.
Government provides public services and makes policies to guide the economy.
The central bank is an institution that controls money supply and regulates banks.
However, it is not considered one of the primary economic agents because it does not directly decide what, how, and for whom to produce.
Instead, it manages monetary policy and supervises the financial system.
Therefore, the option that is not an economic agent is the central bank.
Answer:A. Central Bank.
