Which statement is true about cloud deployment models?

Infrastructure dedicated to a single organization describes a private cloud, not a public cloud - public clouds are multi-tenant environments hosted and operated by third-party providers for many customers simultaneously.

Public clouds are generally less expensive than private clouds because providers achieve economies of scale across large customer bases, eliminating the need for organizations to fund dedicated hardware capital expenditure.

A hybrid cloud combines private and public cloud environments, allowing workloads and data to be shared or moved between them. This model lets organizations keep sensitive workloads on a private infrastructure while leveraging public cloud resources for scalability or less-sensitive tasks.

Public clouds are not inherently less secure than private clouds - major providers maintain extensive compliance certifications, encryption, and access controls under shared-responsibility models that can meet or exceed typical on-premises security postures.
