What describes one of the major economic benefits of free trade between countries?

One of the major economic benefits of free trade between countries is the enhancement of efficiency and productivity through comparative advantage. By allowing countries to specialize in the production of goods and services they can produce most efficiently, free trade enables a more optimal allocation of resources. This specialization leads to lower prices for consumers, increased variety of products, and overall economic growth. Additionally, free trade can stimulate innovation and competition, further benefiting economies involved.
