Which market involves the supply of and demand for goods within one country?

The domestic market is defined as the marketplace within a single country's borders where goods and services are bought and sold. In this market, economic activities are confined to the local economy, and transactions occur between buyers and sellers who operate within the same nation. The interactions of supply and demand in the domestic market reflect the preferences, needs, and financial capabilities of consumers residing in that country, thus affecting local businesses, employment, and economic growth.

In contrast, the global market encompasses international transactions and involves the exchange of goods and services across multiple countries, catering to a broader audience. The terms "new market" and "expansion market" typically refer to strategies related to entering or growing within specific markets rather than defining the nature of the market itself, focusing more on market dynamics rather than the geographical scope of supply and demand. This underscores the reason why the domestic market is the correct choice, as it explicitly describes the context of supply and demand limited to one country.
