Answer:
B. Comparative advantage
Step-by-step explanation:
Comparative advantage is when a country or company can produce goods using fewer resources compared to its rivals. It means the product will cost much less when produced by the country with a comparative advantage.
A comparative advantage means that a country will produce more output of a product when using similar inputs as rivals. The country or company can, therefore, avail the product in the market at a lower cost. Other countries stand to gain when importing products from countries with a comparative advantage than when they manufacture.
