Which of the following is NOT a type of negotiable instrument?

A bill of sale is not classified as a negotiable instrument. Negotiable instruments are financial documents that guarantee the payment of a specific amount of money to a specified person or the bearer, and they include checks, cash, and promissory notes. These instruments can be transferred from one party to another, allowing for easier transactions and the passing of rights to receive payment.

In contrast, a bill of sale serves as a legal document that provides evidence of the transfer of ownership of personal property from one individual to another. It does not function as a payment guarantee or represent a right to receive funds. The nature and purpose of a bill of sale differ significantly from the characteristics that define negotiable instruments. Therefore, this distinction solidifies why a bill of sale is the correct response to the question.
