Question

the goal of a market economy is to
sustain self - sufficiency.
preserve traditional customs.
create equality within a society.
promote free economic choices.

Explanation:

A market economy is characterized by the freedom of individuals and businesses to make economic decisions such as what to produce, how to produce, and for whom to produce, based on supply and demand. "Sustain self - sufficiency" is more related to a self - sufficient or closed - economy model, not a market economy. "Preserve traditional customs" is about cultural preservation, not economic goals. "Create equality within a society" is a social goal that a market economy doesn't necessarily aim to achieve (in fact, market economies can lead to income inequality). "Promote free economic choices" aligns with the core idea of a market economy where consumers and producers have the freedom to choose in the market.

Answer:

D. promote free economic choices.
