What type of economy is an economic system in which private business can operate freely with minimal state control

The correct answer is - market economy.

The market economy type is an economy type in which everything, or almost everything is in the hands of private owners. The government has little control over them, and the control is only in the legislative department, so that they can assure that criminal activities and neglect of the workers wouldn't take place.

In the market economy, the private businesses have the right to choose what they will produce, how will they do that, how many people will they employ, what amount of goods or services they will produce or provide. They also are able to trade not only on the home market, but all around the world where there is demand for their goods and services.

the great wall of china worked as a defense for the feudal states of the zhou dynasty to the north. during the warring states period more walls were put up to defend the borders of the different kingdoms. it was semi successful because despite the wall, the mongols eventually conquered china also the great wall provided protection to the economic development and cultural progress, safeguarded the trading routes such as the silk road, and secured transmission of information and transportation. @jayxboof
