Answer:b. condition in which people's wants outstrip the limited resources available to satisfy those wants
Step-by-step explanation:
Economist believes that scarcity doesn't exist because people are poor or rich but it because we always want more than what we have as a result the amount of resources available becomes insufficient to fulfill all our desires .
Those who already have more still yearn for something more than what they have , the one who has a million wishes they could have five millions and we keep taking and taking in more and more goods and services .
Those who are poor desire to have more of the goods and services than the little that they possess.
As a result of this action we put more demand on the available resources and they become insufficient to fulfill all our wants.
