Answer:
D) society is getting the maximum benefits from its scarce resources.
Step-by-step explanation:
In free market economies (or capitalist economies), efficiency is measured by how much benefits can be obtained by using scarce resources. The higher the benefits obtained, the more efficient societies are.
No country is purely capitalistic or pure socialist, but some tend to be more capitalistic (e.g. US) while others tend to be more socialistic (e.g. North Korea). Capitalistic countries favor free markets and less government intervention, and that usually results in higher income inequalities, higher unemployment, but also higher total wealth. That is why social safety nets are established in capitalistic countries, e.g. Social Security, Medicare, welfare, food stamps, etc.
