Final answer:
The dollar value of all final goods, services, and structures produced in a country in a year is known as Gross Domestic Product (GDP). Therefore, the correct option is A.
Step-by-step explanation:
GDP is a key indicator of a country's economic performance and is used to assess the overall health and size of its economy. It includes the value of goods and services produced within a country's borders, regardless of the ownership of the production factors.
Gross National Product (GNP) (option B) includes the value of goods and services produced by a country's residents, both domestically and abroad. Franchise (option C) and profit motive (option D) are not directly related to the measurement of a country's economic output.
Therefore, the correct option is A.
