The correct answer is C. A source document (B) is a receipt, an invoice, a cancelled check, or other documentary evidence that helps establish the facts of a transaction so that the transaction can be analyzed and a journal entry can be made in the journal. A trial balance (C) is a listing of all the accounts with debit or credit balances, listed in financial statement order, divided into debit and credit balances, and showing a total for all debits and a total for all credits. A chart of accounts has neither totals nor debit or credit balances for accounts shown. A chart of accounts has little to do with the process of analyzing a transaction (D).
