Answer: C. can help promote personal wealth.
In a mixed market economy, the government and private individuals are involved in the economy. i.e., they work mutually in the creation of wealth. Generally, a mixed market system involves both capitalism and socialism. In other words, the monopoly of the government is non-existent and private properties are protected. With this, there are few restrictions as regards the level of economic freedom enjoyed by private individuals. Most countries today practice mixed market economies and are regarded as mixed economies. In summary, a property owned by an individual in a mixed economy can be used to promote personal wealth without fear of government intervention.
