Answer:
C, The unsold additions to inventory at an appliances store.
Explanation:
GDP = Gross DOMESTIC Product
Since the unsold additions are not sold, there's no money coming from it, thus it is not counted in GDP.
Bonus: If you order clothes from Thailand, that is called GNP. It counts as Thailand's GDP because the money is going into the country, and it counts as America's GNP as you are buying goods from another country.
