Concept:Economics is concerned with the efficient allocation of limited resources to meet unlimited human wants.
Explanation:Human wants are unlimited, but the resources needed to satisfy them are scarce.
Scarcity arises because resources are limited in relation to the demands placed on them.
As a result, economists study how best to allocate these scarce resources among competing uses.
Controlling population growth is not the main focus; it is a demographic issue.
Redistributing income is a matter of fiscal policy, not the core concern of economics.
Satisfying all human wants is impossible because wants always exceed available resources.
Therefore, the central task of economics is to make choices about resource allocation.
Answer:D. Allocate scarce resources to satisfy human wants.
