What represents common forms of nonexchange transactions?

The correct choice highlights nonexchange transactions, which occur when one party provides a good or service to another party without receiving equivalent value in return. In the context of governmental accounting, common forms of these transactions include tax revenue and intergovernmental grants.

Tax revenue represents funds collected by government entities from citizens and businesses, which are utilized for public services and infrastructure without a direct return of services or products to the taxpayer. Similarly, intergovernmental grants represent funds received by one level of government from another, such as federal grants to state or local governments. These funds are often allocated for specific purposes, again without a direct exchange of goods or services.

In contrast, sales revenue and service fees involve direct exchange transactions, where goods or services are provided for payment. Interest income and dividends represent returns on investments, and investment sales and property rental involve exchanges where the government is receiving value in return for property use or sale. Thus, these forms focus on exchanges rather than the nonexchange nature of tax revenue and grants, solidifying why the selected answer accurately reflects common nonexchange transactions in governmental accounting.
