Answer:
2.Unit of account
Explanation:
Money has three functions: as a store of value, as a unit of account, and as medium of exchange.
Money acts as a unit of account because it provides a measure of the value of the different goods and services produced within an economy.
For example, in the U.S., the value of goods and services are measured in dollars. A house may cost $100,000, while a meal at McDonalds can cost $10 or less.
