Correct arrangement

  • PaaS
  • SaaS
  • IaaS

Explanation

The correct arrangement maps three Microsoft 365 services to their cloud models: the first service (likely Azure App Service or similar) is PaaS because Microsoft manages the underlying infrastructure and runtime while users manage applications; the second service (likely Microsoft 365 apps such as Exchange Online, Teams, or SharePoint Online) is SaaS because the entire application is managed and delivered by Microsoft with no user management of infrastructure or platform; the third service (likely Azure Virtual Machines or similar) is IaaS because users are responsible for managing the OS, middleware, and applications while Microsoft provides virtualized hardware. These distinctions reflect the fundamental shared-responsibility model differences across the three cloud service types.
