Military goods purchased by the government are

A) not included in GDP.
B) measured in GDP by their cost of production.
C) measured in GDP by how much their goods add to the economic well-being.
D) measured in GDP only if the government sells these goods to another country.

Military goods purchased by the government are included in GDP through their cost of production because they are considered a final good or service that adds value to the economy. However, they are not included in GDP through their economic well-being because they do not provide a direct benefit to consumers in the market. Additionally, the government selling the goods to another country does not determine their inclusion in GDP.
