Answer:
The correct answer is letter "B": a comparative advantage with coffee.
Explanation:
Comparative advantage is the advantage an individual, organization or country has over others. It does not mean the individual has an absolute advantage over its competitors but it has found ways to produce at lower opportunity costs than its rivals. The concept was introduced by English economist David Ricardo (1772-1823) who believed countries should produce those goods they are best at manufacturing and import those that it is not efficient at producing.
Therefore, Costa Rica has a comparative advantage over Canada on coffee production since that commodity easily grows in Costa Rica.
