Which of the following bids includes many specifications that only one manufacturer can meet?

A restrictive bid includes many specifications that only one manufacturer can meet because it is designed to limit the competition to a specific supplier or product that meets very particular needs. In situations where an organization has unique requirements, such as specialized equipment or specific capabilities that only one manufacturer can provide, a restrictive bid allows the organization to ensure they receive exactly what is needed without the confusion or disparity that can arise from evaluating multiple vendors.

This approach can often lead to a more straightforward procurement process but may limit the potential for cost savings that can arise from competitive bidding. Open bids, competitive bids, and negotiated bids typically involve a broader range of suppliers meeting varied specifications, which allows for more competition and potentially better pricing, but that is not the goal of a restrictive bidding process.
