Which of these cloud deployment models is a combination of public and private cloud storage?

A hybrid cloud is a cloud computing environment that uses a mix of on-premises (private cloud) and third-party (public cloud) services with orchestration between the two platforms. This model allows workloads to move between private and public clouds as computing needs and costs change, giving businesses greater flexibility and more data deployment options. The fundamental characteristic of a hybrid cloud is its composition of at least one private cloud and at least one public cloud, which are bound together by technology enabling data and application portability.

A. Private: A private cloud is a single-tenant environment, meaning the infrastructure is provisioned for exclusive use by a single organization. It is not a combination of different cloud types.

B. Public: A public cloud is provisioned for open use by the general public and is owned and operated by a third-party cloud service provider. It is not a combination model.

C. Community: A community cloud is shared by several organizations with common concerns (e.g., mission, security requirements, policy), but it is not inherently a mix of public and private infrastructures.
