Which of the following must contractors provide to secure a contractor’s license bond?

To secure a contractor's license bond, a surety bond is required. This type of bond serves as a guarantee that the contractor will fulfill their obligations as specified in their contracts. Essentially, it protects clients and ensures that contractors comply with state laws and regulations. If the contractor fails to complete a job or meets a legal obligation, the surety bond provides compensation to the affected parties, allowing them to recover financial losses.

The other options, while relevant in some contexts, do not directly fulfill the requirement for obtaining a contractor's license bond. A detailed project plan, a financial statement, and a certificate of insurance may be necessary for various aspects of running a contracting business or for specific projects, but they are not the mechanisms that operate as the bond itself. The surety bond is fundamentally what secures the license and provides both the contractor and clients a level of protection and assurance in the contracting process.
