Final answer:
The law of increasing opportunity cost states that as the production of a good or service increases, the marginal opportunity cost of producing it also increases.
Step-by-step explanation:
The law of increasing opportunity cost states that as the production of a good or service increases, the marginal opportunity cost of producing it also increases. This is because resources are better suited for producing certain goods and services instead of others.
For example, if a government spends more on reducing crime, the initial increase in opportunity cost may be relatively small. However, as additional resources are allocated to reducing crime, the opportunity cost increases significantly.
This concept is illustrated by the curved shape of the production possibilities curve (PPC), which shows that as more resources are added to a specific area of production, the increase in opportunity cost becomes steeper. Therefore, option b) is the correct statement that accurately describes the concept of increasing opportunity cost.
