Answer:
The answer is C. black market.
Step-by-step explanation:
Closed market is a market where the government controls the prices and availability of goods and services. This is not an example of capitalism.
Stock market is a market where shares of companies are bought and sold. This is an example of capitalism, but it is not an example of capitalism existing within a command economy.
Open trade market is a market where goods and services can be freely traded between countries. This is not an example of capitalism.
Black market is a market where goods and services are traded illegally. This is an example of capitalism existing within a command economy because it is a market where individuals are able to buy and sell goods and services without government interference.
In a command economy, the government controls the means of production and sets prices. This means that there is no free market for goods and services. However, black markets often emerge in command economies as a way for individuals to circumvent government controls. In a black market, goods and services are traded illegally, often at prices that are higher than the government-set prices. This allows individuals to earn a profit, which is a key element of capitalism.
Here are some examples of black markets that have existed in command economies:
The Soviet Union had a black market for food, clothing, and other goods.
China had a black market for cigarettes, alcohol, and other goods.
Cuba has a black market for goods such as electronics, food, and medicine.
Black markets are often seen as a sign of economic problems in a command economy. However, they can also be seen as a sign of the resilience of capitalism. Even in a system where the government controls the means of production, individuals will find ways to trade goods and services in order to earn a profit.
