Which service provides storage for office productivity software in the cloud?

The choice of Microsoft 365 as the correct answer is appropriate because it offers a comprehensive suite of office productivity tools, including Word, Excel, PowerPoint, and OneNote, all accessed via the cloud. With Microsoft 365, users can not only create and edit documents online but also store them securely in the cloud, allowing for easy access from various devices. This integration of productivity software and cloud storage makes it a go-to solution for many businesses and individuals seeking collaborative features and reliable data backup.

While Google Workspace also provides a similar service, it is essential to note that the question specifically asked for a service, and Microsoft 365 encapsulates various Office applications and storage options under one umbrella, offering a more traditional office software experience. iCloud primarily focuses on file storage and syncing for Apple devices but lacks a full suite of office productivity tools like word processors or spreadsheet applications. Dropbox is primarily a file hosting service that is excellent for storing and sharing files but does not provide dedicated office productivity software. Therefore, Microsoft 365 stands out as the ideal choice for cloud-based office productivity and storage solutions.
