The right answer is option C. can be computed
as either the revenue firms receive from the sales of goods and
services or the payments firms make to factors of production.
Explanation: GDP is the market value of all
goods and services produced in a country in a given year. We need
to consider either the revenue of the firm from the sales of goods
and services or the factor payments made by the firm to calculate
GDP. This is because the value of the revenue and the factor
payments of the firm is equal. Counting both will result in the
duble counting of GDP.
