Which of the following is an acceptable form of bond?

The correct choice indicates that a driver's license, signature, or cash has historically been acceptable forms of bond. In many jurisdictions, these forms are used to ensure that an individual has a financial stake or commitment to appear in court or fulfill a legal obligation.

Specifically, a driver's license serves as a form of identification, affirming the individual's identity and residency, while a signature evidences the person's agreement to the terms associated with the bond. Cash, being a tangible asset, provides immediate assurance to the court or law enforcement that the individual has the means to comply with the required obligations. These forms are practical and easily verifiable, making them commonly accepted in legal processes.

In contrast, other options may not fulfill the legal requirements for a bond. A credit card may offer some financial backing but does not provide the same level of certainty and immediacy as cash. Personal checks can be unreliable due to potential issues such as insufficient funds. While a bank guarantee does represent a firm financial backing by a financial institution, it may not always be acceptable in jurisdictions that have specific regulations regarding bonds. Hence, the identification and cash options covered in the correct choice are well-established practices in the context of bonds.
