The correct option is A Journal
After analyzing and preparing business documents, the transactions are then recorded in the books of the company. A journal entry is the recording of a business transaction in the journal. A journal entry shows all the effects of a business transaction as expressed in debit(s) and credit(s) and may include an explanation of the transaction. A transaction is entered in a journal and before it is entered in ledger accounts. In double-entry accounting transactions are recorded in the journal through journal entries. A journal, also known as Books of Original Entry, keeps records of business transactions in a systematic order. Transactions are recorded in the journal in chronological order, i.e. as they occur; one after the other.
