The correct answer is C. Capitalism.
In a capitalist economy, the consumer is the king. Businesses compete to provide goods and services that consumers want, and consumers have the freedom to choose which businesses they want to support. This system is based on the idea that the best way to meet people’s needs is to allow them to freely choose what they want to buy.
In a socialist economy, the government controls the means of production and distribution. This means that the government decides what goods and services will be produced, how they will be produced, and who will get them. In a socialist economy, the consumer does not have as much freedom to choose what they want to buy.
In a mixed economy, the government and private businesses both play a role in the economy. In a mixed economy, the government may provide some goods and services directly, such as education and healthcare. However, the government also allows private businesses to operate in the economy. In a mixed economy, the consumer has some freedom to choose what they want to buy, but the government also plays a role in determining what goods and services are available.
Therefore, the only economy in which the consumer is called “the Emperor” is capitalism.
