A defense contractor builds a cloud with on-demand self-service provisioning, resource pooling and measured usage. The infrastructure is provisioned for the exclusive use of that one organization and its business units, whether it sits in the contractor's own facility or in a third-party hosted facility. Which deployment model is this?

Short Explanation
It's like a private dining room in a restaurant: someone else may own the building, but nobody else eats at your table. Private cloud is about exclusive use, not about whose building it's in. The trap is "third-party facility" — that pushes you toward public or hybrid, but location doesn't change who the cloud serves.
Full Explanation
NIST SP 800-145 defines a private cloud as infrastructure provisioned for exclusive use by a single organization comprising multiple consumers, such as business units. It may be owned, managed and operated by the organization, a third party or a combination, and it may exist on or off premises. The scenario still exhibits the essential cloud characteristics of self-service, pooling and measured service, and the infrastructure serves only the contractor, so it is a private cloud regardless of which facility houses it. Public cloud is ruled out because public infrastructure is provisioned for open use by the general public; a third-party host operating hardware dedicated to one organization does not make it public. Community cloud is ruled out because it serves a specific community of organizations with shared concerns, and the stem states exclusive use by one organization, with no suppliers granted access. Hybrid cloud is ruled out because hybrid means two or more distinct infrastructures bound together, not a single private cloud whose location happens to be off premises. Exam caveat: watch for wording that tempts you to classify by location or ownership; NIST classifies deployment models by the consumers the infrastructure serves. Operational check: confirm in the hosting contract that hardware and management planes are dedicated to the organization and that no other tenant shares them.
