Explanation:

Identify the characteristics of Office 365

Office 365 (now Microsoft 365) is a suite of productivity applications (such as Word, Excel, PowerPoint, and Outlook) hosted in the cloud and delivered directly to end-users over the internet. Users do not manage the underlying infrastructure, operating systems, or application development frameworks.

Match with cloud computing service models

• SaaS (Software as a Service): Delivers fully functional applications directly to end-users over the internet.
• PaaS (Platform as a Service): Provides a platform and environment for developers to build and deploy applications.
• IaaS (Infrastructure as a Service): Provides fundamental computing resources like virtual machines, storage, and networks.
• Application streaming: A method of delivering applications on-demand to client devices, which is a delivery mechanism rather than a primary cloud service model.

Since Office 365 is a fully functional software application suite managed entirely by the provider, it is a classic example of Software as a Service (SaaS).

Answer:

• PaaS
• Application streaming
• IaaS
• SaaS (Correct answer)
