The correct answer is A. significant differences still exist among national markets.

Explanation:

National products or local products are products whose exchanges are usually established in the dimension of the nation understood as an independent State. The national market is formed when the economic space of that State responds to the concept of market unity, that is, when it is unified and essentially obeys the same laws (such as commercial legislation or the regulation of property rights) , taxes, pesos and measures, currency, etc.

It opposes on the one hand the concept of international market, typical of international trade; and on the other to the local market, regional market, regional market or other divisions of lower spatial level (locality, region, region). Supranational integration can lead in practice to the integration of national markets, as in the European Union, which implies for all its members the customs union and the coordination of economic policies and for several of them the monetary union (the euro ).

The scope of the national market or internal market is that used for national accounting, in which the different quantities denominated Gross National Product are expressed (the one produced by nationals of a state both inside and outside their internal market), Gross Domestic Product (the one produced in its internal market by both nationals and foreigners), National Income, etc.
