Answer:
B). Not all resources are equally effective in the production of all goods.
Step-by-step explanation:
Comparative advantage is the economic term that is associated with the economy's potential to manufacture goods at a relatively lower opportunity cost as compared to the other trade participants. Such a situation primarily arises due to the reason that 'not all the resources possessed are equally efficient/effective in the production of each and every good' and therefore, the ability or advantage would be possessed by those who are able to produce goods and services at a comparatively reduced opportunity cost. Therefore, option B is the correct answer.
