The correct answer is C) Free-market and command.

A mixed economy is used by the United States, as it has elements of both of these type of economic systems.

For example, the US has elements of free-market when citizens have the ability to decide how they spend their money. Along with this, businesses have the ability to choose what products they make and how much they charge for these goods/services.

The US also has elements of a command economy, as the government has agencies that control some elements of the economy. For example, the government can regulate trusts and monopolies and stop them from operating within the US.
