Answer:
<em>a. law of increasing relative cost</em>
Explanation:
In economics, the law of increasing costs <em>is a theory which states that once all production factors (land, labour, capital) are at maximum output, it will cost more than average to produce.</em>
As production increases, the opportunity cost will also increase.
In such a nut-shell, markets and countries are trying to strike a balance on how to handle resources whilst using the goods to achieve the best possible productivity and revenue.
The producers can create their maximum combination of goods,
as long as the producers address the consumer desires. In this way, they may
likely be efficient with the resources they get and use in a way of creating
goods that will be useful and that it won’t go to waste.
