Answer:
B. How can available resources be used efficiently?
Explanation:
In order to maximize the efficiency of the limited productive resources a society needs and wants, we must ask three main questions (what to produce, how to produce and for who to produce). All economic systems (free-market, mixed, command, and traditional) seek to solve these three questions.
<u>To determine how a society will produce goods and services we must ask how can available resources be used efficiently, </u>which resources are adequate to produce certain good, and how it will be produced, whether it is by machines or people to maximize the capacity of production.
