Which statement best defines a medium of exchange?

• A. A money that buyers are willing to accept in payment.
• B. A standard numerical monetary unit for pricing.
• C. A claim on a commodity.
• D. The physical cash in circulation.

Answer: (A)

A medium of exchange is money that buyers are willing to accept in payment, which is what lets people trade goods and services without directly bartering each time. The essential idea is acceptability: if sellers trust that the money will be widely accepted in exchange for goods, it makes transactions smoother and faster. This differs from a unit of account, which is about a standard numerical measure for pricing things, and from a claim on a commodity, which describes a form of money tied to a resource or asset. It also isn’t limited to physical cash in circulation, since today many forms of money (like digital payments) can serve as the medium of exchange as long as they are generally accepted.
