a. the sum of balance of trade and the balance of services.
b. the net foreign investment.
c. a component of aggregate supply.
d. the current account balance.

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.
