Explanation

Single-tenancy IaaS satisfies all three requirements simultaneously. IaaS (Infrastructure as a Service) provides access to the underlying infrastructure, giving the organization full control over OS and application-layer software administration - something PaaS and SaaS explicitly abstract away. Single-tenancy guarantees physical isolation of data, meaning hardware resources are not shared with other customers, which is required to demonstrate physical data separation to auditors. Finally, IaaS environments support VPN and remote access configurations needed for MSSPs (Managed Security Service Providers). Option A (Private PaaS) removes OS-level control. Option C (Hybrid SaaS) removes both OS and application control. Option D (Multitenancy DBaaS) shares physical infrastructure across tenants, directly violating the physical separation requirement.
