Answer:
C. a component of aggregate supply.
Explanation:
Net exports represent the difference between the total value of a country's exports and imports. A positive net export value implies a country has a trade surplus, while a negative value is a trade deficit.
Aggregate supply refers to the total value of goods and services produced and supplied to the market by firms at a particular price point over time. In other words, aggregate supply is a country's total output.
Net exports have an element of international trade. It measures what a country buys from other countries versus what it sells to its international trade partners. Aggregate supply on the hand is about a country's domestic production.
