Explanation

NOTE: The answer key lists A (Private PaaS), but this is technically debatable. The requirements - OS and application-level administration, physical separation from other tenants, and remote MSSP connectivity - align more precisely with B (Single-tenancy IaaS). PaaS typically abstracts the OS layer, which conflicts with 'administer at OS level.' Single-tenancy IaaS provides dedicated physical hardware (satisfying data separation), full OS/application control (satisfying admin requirements), and supports remote connectivity for MSSPs. If the exam intends 'Private PaaS' to mean a fully dedicated, privately operated platform where the org controls the underlying stack, it can satisfy the requirements - but IaaS is the more technically accurate answer for OS-level administration with physical tenant isolation.
