Which of the following best explains the function of money as a medium of exchange?

The function of money as a medium of exchange is fundamentally about facilitating trade between parties. Money serves as an accepted method for individuals and businesses to conduct transactions without the complications of bartering. In a barter system, two parties must agree on the value of goods or services being exchanged, which can be cumbersome and inefficient. Money eliminates this barrier by providing a universally accepted currency that can be exchanged for any goods or services, thus streamlining the trade process.

When money acts as a medium of exchange, it enhances the overall efficiency of the economy by enabling transactions to occur more smoothly. This function allows buyers and sellers to engage in exchanges with confidence, knowing that they can utilize money to acquire what they need and can use it to sell their own goods or services. In this context, money’s role in enabling trade is central to a functioning market economy.

The other functions mentioned, like measuring value or serving as an investment tool, relate to different aspects of money’s role in the economy but do not primarily address its core function as a medium of exchange, which is pivotal in facilitating trade.
