Concept: Scarcity is the basic economic problem because human wants are unlimited, but productive resources are limited.
Explanation:Economics begins with the reality that resources such as land, labour, capital, and entrepreneurship are finite.
At the same time, society's wants are endless and keep growing.
This gap between limited resources and unlimited wants creates scarcity.
Scarcity forces individuals, firms, and governments to make choices about how to allocate resources efficiently.
Option A focuses only on supply and demand forces, which is a market mechanism, not the root problem.
Option C refers to the political framework of production, which arises because of scarcity but is not the fundamental problem itself.
Option D deals with income distribution, which is an economic policy goal rather than the core problem.
Option B correctly identifies scarcity of productive resources relative to unlimited wants as the fundamental problem.
Answer: B. The scarcity of productive resources relative to society's unlimited wants.
