Money can be used as a standard unit for pricing and trade efficiency.

• A. A Measure of Value
• B. Storage of Wealth
• C. A Medium of Exchange
• D. Durable

Answer: (C)

Money being a standard unit for pricing and overall trade efficiency hinges on its role as a medium of exchange. When prices are set in money, buyers and sellers don’t have to barter or scramble for goods to match each other’s wants; they simply trade money for goods or services. This common medium streamlines transactions, reduces transaction costs, and speeds up exchanges, which is why it boosts trade efficiency. The other ideas are related to money’s functions but don’t directly capture the mechanism that most clearly drives faster, smoother trades in everyday commerce.
