Answer:
d. final goods and services produced annually within a country's borders.
Explanation:
Counting intermediate and final goods and services will make the intermediate count twice or more times as they are included in the cost of the final goods.
Also, the gross domestic product is measured quarterly and annually. Not monthly.
It counts within the country's border to measure the activity of each State in the world. Doing so allows checking which law and institution allow for economic growth and which doesn't.
