Answer:
D. all modern economies.
Explanation:
Mixed economy is a system in which the planned production methods operate simultaneously, when the state acts as a player - acting directly in production - but also the model of market production, when there is production conducted by the private initiative.
In a mixed economy, state production is driven by state-owned enterprises in strategic areas such as oil production. Private initiative operates in any area. In this way, we can say that in a mixed economy system people are allowed to open their own businesses, since this is no longer a prerogative of the State. Virtually all capitalist nations are to a greater or lesser extent mixed economies, since in addition to private action, the state operates in some sectors. This is seen in the American, European and Asian economies.
