The correct answer is: D. Net domestic product
Net domestic product (NDP) is the total market value of all final goods and services produced within a country’s borders in a specific time period, minus depreciation. It is calculated by subtracting depreciation from gross domestic product (GDP).
GDP is the total market value of all final goods and services produced within a country’s borders in a specific time period. It is calculated by adding up the value of all goods and services produced by domestic residents, regardless of where they are located.
Depreciation is the decrease in the value of capital goods over time due to wear and tear. It is calculated by multiplying the value of capital goods by the depreciation rate.
NDP is a more accurate measure of a country’s economic output than GDP because it takes into account the fact that capital goods wear down over time.
