Final answer:
The business should record a journal entry A. debiting Accounts Receivable and crediting Service Revenue for $3,200.
Step-by-step explanation:
The correct journal entry for the business to record the transaction would be:
Debit Accounts Receivable for $3,200
Credit Service Revenue for $3,200
When the business provided legal services and billed the client $3,200, Accounts Receivable is debited (increased) because the business has an account receivable from the client. At the same time, Service Revenue is credited (increased) because the business has earned revenue by providing the legal services.
