An example of comparative advantage would typically involve a situation where a country can produce a good at a lower opportunity cost compared to another country.
In this case, the option that best aligns with the concept of comparative advantage is:
"higher-priced corn grown in Mexico using labor-intensive traditional techniques."
This implies that Mexico has a comparative advantage in producing corn using traditional methods that may be more labor-intensive, focusing on their local efficiencies and capabilities rather than competing directly with the low-cost mechanized production in the U.S. The comparative advantage arises from the unique resources (like labor and techniques) that Mexico has in this context.
