Which type of trade occurs within a nation's own borders?

Local trade refers to the exchange of goods and services that occurs within a country's own borders. This type of trade typically involves transactions between businesses and consumers within the same region, city, or locality, emphasizing proximity and often lower transportation costs compared to trade that spans international borders. Local trade is crucial for supporting regional economies and fostering community relationships.

In contrast, international trade encompasses the exchange of goods and services across countries, while import trade specifically pertains to goods brought into a country from abroad, and export trade relates to goods sent out of the country. Thus, local trade is distinct and specifically highlights economic activities that remain confined to national borders, making it the correct response to the question.
