How did the first cash registers 'register' a transaction in terms of accounting entries?

Recall the rules of debits and credits: An increase in an asset account (Cash) is recorded as a debit, while an increase in a revenue account (Sales Revenue) is recorded as a credit.

Analyze the incorrect options: For example, recording a debit to Sales Revenue and a credit to Inventory does not align with the transaction type, as Inventory is not directly involved in cash register transactions. Similarly, Accounts Payable is irrelevant here since it pertains to liabilities, not cash sales.
