In a planned economy the economic problem of what shall be produced is determined primarily by

The correct answer is: B. direction by the Government.

In a planned economy, the government is responsible for determining what goods and services will be produced. This is done through a process of planning, which involves setting production targets and allocating resources. The government may also use price controls and subsidies to influence the production of goods and services.

The other options are incorrect because:

• Computers cannot decide what consumers want. Consumers are the ones who ultimately decide what goods and services they want to buy.
• The pattern of consumer’s spending is not the only factor that determines what goods and services will be produced in a planned economy. The government also takes into account other factors, such as the need for national security and the need to promote economic development.
• The independent decisions of entrepreneurs are not the primary factor that determines what goods and services will be produced in a planned economy. The government is the one who makes the decisions about what goods and services will be produced.
