Which of the following best describes a security in financing terms?

• A. A physical asset used as collateral
• B. A promissory note
• C. Any type of investment such as stock, bond, debenture, or interest
• D. An agreement to distribute profits

Answer: (C)

In financing terms, a security is a tradable financial instrument that represents an ownership interest or a creditor relationship with an issuer. Stocks and bonds are the classic examples, with debentures falling under the debt instrument umbrella. A physical asset used as collateral is a security interest or collateral arrangement, not a security instrument itself. A promissory note is primarily an IOU as a debt obligation and isn’t automatically treated as a security in the broad sense of tradable investments. An agreement to distribute profits describes a contractual arrangement like a partnership or venture, not a traded investment instrument. Because a security covers the wide range of investable instruments, including stock, bond, debenture, or similar interest, this option best describes what a security is.
