They're a form of tax in which the users of public services are charged a specified fee to cover some of all of the cost of providing that service.

• A. Tariffs
• B. Excise tax
• C. User Fees
• D. Property tax

Answer: (C)

User fees are payments charged to those who use a public service, intended to cover all or part of the cost of providing that service. This approach ties the payment directly to usage—for example, tolls on roads, park entrance fees, or library printing charges—so the people who benefit from the service contribute to its cost.

Tariffs are duties on imported or exported goods, not on the use of public services. Excise taxes are taxes on specific goods like alcohol or gasoline, again not tied to service usage. Property tax is levied on the value of real estate and funds general local government, not a particular service based on use.
