The sum of production in the three sectors within a country during in particular year is called :

Question

Accepted Answer

The correct option is 3:

The correct option is 3: GDP.

Gross Domestic Product (GDP) is the standard and most fundamental measure used to represent the total economic activity occurring within a country's geographical borders during a specified time period, typically one year. The question asks for the sum of production in the three sectors—Primary (agriculture), Secondary (industry), and Tertiary (services)—which is precisely the definition of GDP as calculated by the output or value-added method. GDP calculates the market value of all final goods and services produced *within the domestic territory* of a country. By summing up the value added by these three sectors, we arrive at the final GDP figure, making it the perfect measure for the country's total internal production.

The incorrect option is 1: GNP.

Gross National Product (GNP) is distinct from GDP because it focuses on the production generated by the residents and enterprises of a country, regardless of where that production occurs. While GDP is a territorial concept (within the country's borders), GNP is a national concept. GNP is calculated by taking the GDP and adding Net Factor Income from Abroad (NFIA), which includes the income earned by national residents from overseas minus the income earned by foreign residents within the country. Since the question specifically asks for the sum of production *within a country*, GNP, which includes foreign income, is not the most precise answer.

The incorrect option is 2: NNP.

Net National Product (NNP) is derived from GNP by subtracting depreciation (also known as Consumption of Fixed Capital). Depreciation accounts for the wear and tear or obsolescence of capital goods during the production process. NNP, therefore, represents the net output available for consumption and investment after replacing the used capital. Since the question refers to the *sum of production* without any mention of deducting capital consumption or depreciation, NNP is an inappropriate answer.

The incorrect option is 4: GNI.

Gross National Income (GNI) is essentially the same measure as GNP, as it calculates the total income earned by a country's people and businesses, including factor income received from abroad, but excluding factor income paid to non-residents who contribute to the domestic economy. While in practice GNP and GNI yield almost identical figures and are often used interchangeably, the term GNI focuses on income flows, whereas the question explicitly asks for the *sum of production* (output/value-added), which is the precise definition of GDP.
