Answer: c. may be used to settle an accounts receivable.
Explanation: A promissory note is defined as a financial instrument that contains a written promise by the note issuer or maker to pay the note payee a definite sum of money at a specific future date or on demand and may be used to settle an accounts receivable (the balance of money due to a firm for goods or services delivered or used but not yet paid for by customers and are listed on the balance sheet as a current asset).
