Concept:The total output produced within a country's borders is known as the gross domestic product (GDP).
Explanation:GDP is the total money value of all final goods and services produced within the domestic territory of a country during a specific period, usually one year.
It counts earnings of citizens and foreign investors whose production takes place within the country.
It does not include earnings from citizens' investments abroad, since such income is generated outside the country's territory.
GDP should be distinguished from gross national product, which adjusts for net income from abroad.
Since the question refers specifically to production within domestic territory, gross domestic product is the correct term.
Answer:B. gross domestic product
