Step-by-step explanation:
The correct answer is (a) Demand. Demand is not one of the four principles on which the U.S. economic system is based. The four principles are:
Private Property: This principle refers to the right of individuals and businesses to own and control their property, including land, buildings, and other assets.
Profit: This principle is based on the idea that individuals and businesses have the right to pursue profits and financial success through their economic activities.
Freedom of Choice: This principle ensures that individuals have the freedom to make their own economic decisions, including what to buy, sell, or invest in.
Economic Freedom: This principle encompasses the rights and freedoms individuals have in the economic system, including the ability to own property, make contracts, and engage in voluntary exchange.
These principles form the basis of the U.S. economic system and help to promote economic growth, individual freedom, and the creation of wealth.
