Concept:Economics studies how people make choices because resources are limited while wants are unlimited.
Explanation:Resources in every society are scarce, meaning they are inadequate to produce everything people want.
Since no society can satisfy all wants, individuals and governments must choose how to use limited resources.
Economics focuses on the best way to allocate these scarce resources among competing uses.
It also guides decisions on what to produce, how to produce it, and for whom to produce.
Option A is not the main concern because simply ranking wants does not solve the problem of scarcity.
Options C and D are unrealistic because scarcity prevents the satisfaction of every person or production of all goods.
Therefore, economics deals directly with making choices when resources are inadequate.
Answer:B. make choice when resources are inadequate.
