What best describes the concept of comparative advantage?

Comparative advantage refers to the inherent ability of a country (or entity) to produce a good or service at a lower opportunity cost compared to another country. This concept implies that even if one entity is less efficient in producing all products, it can still benefit from specializing in the production of the good for which it has the lowest opportunity cost compared to others.

When a country can produce a good at a lower opportunity cost than another, it means that it sacrifices less of other goods when it produces this specific good. This leads to more efficient global production and trade, allowing all parties involved to benefit from specialization. Thus, the focus is on the relative efficiency of producing different goods rather than an absolute measure of production costs.

The other options reflect misunderstandings of the comparative advantage concept. Some describe cost advantages or other economic principles that do not capture the essence of comparative advantage. Understanding comparative advantage is crucial for grasping international trade dynamics and the benefits of specialization.
