Answer: D) eliminates the need for trade with other nations
Explanation:
Having comparative advantage on the production of a good or service means that a country can produce that good or service cheaper and be able to exchange it for other goods and services that other countries are offering.

This means that trade with other countries is still needed to provide those goods that they need but find it expensive to produce.
