Answer: The correct answer is c. Expenses are reported on the income statement when cash is paid.
Explanation: Matching principle states that expenses are matched with the related revenue in the same period, that is, expenses incurred to generate related revenue are recorded during the same time interval the related revenue is recorded in order to show the true and fair position of the profitability of the company.
Based on the above definition, only option C does not align with the matching principle because expenses should be recorded in the income statement when incurred and NOT when cash is paid. If it is recorded when cash is paid, it means cash basis of accounting is being applied.
