The correct answer is Tenant.

A Tenant is an independent client organization that consumes a shared pool of compute and storage in a multi tenant hosting environment. The term refers to logical separation of each customer's data and settings while the provider shares the underlying infrastructure and management across multiple tenants.

Partner is incorrect because that term describes a business relationship or reseller and not a customer organization using shared hosting resources.

Hybrid cloud is incorrect because that phrase describes a deployment model that combines public and private cloud resources and not the identity of client organizations in a shared environment.

Auditor is incorrect because an auditor is a person or team who assesses compliance and controls and not a client organization that occupies compute and storage resources.
