Economics is a social science that studies how individuals, institutions, and society may:

A. Expand the amount of resources available to them

B. Attain a minimum level of production

C. Best use resources to maximize satisfaction of economic wants

D. Reduce the amount of goods and services they need

The correct answer is letter "C": Best use resources to maximize satisfaction of economic wants.

Explanation:

Scarcity is the elemental economic problem by which individuals have unlimited needs but only limited resources to satisfy them. This scenario leads to trade-offs. People will have to sacrifice part of the satisfaction of one good so the satisfaction of another can also be fulfilled.

Scarcity pushes individuals to allocate their resources efficiently.

C. Best use resources to maximize satisfaction of economic wants

Explanation:

Economics is a social science that studies human behaviour in relation to ends and scarce means resulting in alternative uses. This definition by Lord Robbins deals with the basic concept of economics.

Human wants are unlimited however, the resources available to satisfy these wants are limited hence choices have to be made in other of importance for the allotment of the limited resources in satisfying the unlimited wants resulting in scale of preference and opportunity cost.
