A nation's GDP is Multiple Choice C + I + G + (X - M). The sum of value added at some stages of the production process. The total market value of all intermediate goods and services. The total amount of money in circulation.

The correct options are "The sum of value added at some stages of the production process and The total market value of all intermediate goods and services.

Explanation:

GDP is the sum of value added at every stage of production (the intermediate stages) for all final goods and services produced within a region in a given period of time. In other words, GDP is the wealth majorly created by industry activity but the contributions of the households are not left out as well.

However, the second option of "The total market value of all intermediate goods and services," is correct because the real GDP is the monetary equivalent of all the produced goods and services at market prices. The denominator of every production is a function of money.

C + I + G + (X - M)

Explanation:

A nation's GDP is measured by the formula C + I + G + (X - M).

Gross Domestic Product can be defined as the sum of value added at all stages of the production process.

Furthermore Gross Domestic Product can be defined as the total market value of all final goods and services.

However it cannot be defined as the total amount of money in circulation, as that would refer to money supply.
