Which statement is true?

A) GDP tells us what we produce.
B) GDP estimates the value of household and illegal production.
C) Per capita real GDP is found by dividing population by real GDP.
D) International comparisons of per capita real GDP may be made with less caution than comparisons over time within a given country.
E) None of the statements are true.

GDP primarily measures the total value of all goods and services produced over a specific time period within a country's borders, but it does not account for household and illegal production. Per capita real GDP is calculated by dividing real GDP by the population, not the other way around. International comparisons of per capita real GDP require caution due to differences in currency values, living costs, and data collection methods, making such comparisons more complex than temporal comparisons within a single country.
