Which of the following bonds ensures that subcontractors and suppliers will be paid?

A payment bond is specifically designed to ensure that all subcontractors and suppliers involved in a construction project receive payment for their services and materials. This type of bond provides a guarantee that the contractor will pay all parties involved in the project, thus protecting subcontractors and suppliers from the risk of non-payment.

In contrast, other types of bonds serve different purposes. A performance bond, for example, ensures that the contractor will fulfill the terms of the contract but does not directly address payment to subcontractors and suppliers. A bid bond guarantees that the contractor will honor their bid if selected for the project, while a license bond is related to the contractor's legal qualifications to operate within a certain jurisdiction. Therefore, the payment bond is the most suitable choice for ensuring payment to subcontractors and suppliers.
