What is referred to as a Sole Source Supplier?

A Sole Source Supplier is defined as a supplier that is the only provider for a specific resource or product. This means that no other supplier can provide the same item or service, making the sole source critical for businesses that rely on that particular resource. The uniqueness of the supplier in such scenarios can be due to various factors, such as proprietary technology, exclusive contracts, or the supplier's specialized capability that cannot be replicated by others. As a result, businesses often face challenges in terms of pricing, supply assurance, and negotiation flexibility when depending solely on such a supplier.

The other choices do not accurately capture the essence of what a Sole Source Supplier is, as they refer to concepts such as offering multiple options, higher costs, or quality controls, which do not pertain to the exclusivity and the defining characteristic of being the only provider for a specific need.
