Final answer:
The correct adjusting entry for a company that has earned revenue but not yet received cash is to debit Accounts Receivable and credit Sales Revenue, per accrual accounting principles.
Step-by-step explanation:
If a company has earned revenue from selling a product but has not yet received the payment in cash, the correct adjusting entry to record this accrual would involve a debit to Accounts Receivable and a credit to Sales Revenue. This reflects that the company has the right to receive cash for the sale made, which increases Accounts Receivable, an asset account. Simultaneously, recognizing the revenue earned for the sale of the product increases the Sales Revenue account, which is recorded on the credit side in accordance with the accrual basis of accounting.
