Concept:The key phrase "within the borders of a country" points to a domestic measure of production.
Explanation:Gross domestic product (GDP) measures the total market value of all final goods and services produced within a country’s borders in a given period.
It includes production by both residents and non-residents located inside the country.
Gross national product (GNP) instead counts production by citizens of the country, no matter where they are located.
Net domestic product and net national product are obtained after deducting depreciation from GDP and GNP respectively.
Therefore, the term that exactly matches "produced within the borders" is gross domestic product.
Answer:C. gross domestic product
