A Voucher is a formal banking and accounting document detailing a transaction.
It serves as evidence of a transaction, including its amount, date, purpose, and signatures.
Vouchers record both cash receipts and payments in accounting records.
Financial institutions, businesses, and organizations create vouchers to ensure accurate and lawful documentation of all financial dealings.
While pay-in and withdrawal slips are specific to depositing and withdrawing funds respectively, they are limited in scope.
The Profit and Loss Account, in contrast, summarizes income and expenses over a period, and is not a voucher for an individual transaction.
Consequently, option (C) Voucher is correct, as it officially documents transaction specifics.
