Answer:B) Gross domestic product
Explanation:Gross Domestic Product (GDP) is the broadest quantitative measure of a nation's total economic activity. More specifically, GDP represents the monetary value of all goods and services produced within a nation's geographic borders over a specified period of time.
The equation for calculating GDP is: GDP = private consumption + gross investment + government investment + government spending + (exports – imports). For the gross domestic product, “gross” means that the GDP measures production regardless of the various uses to which the product can be put.
