What is the purpose of iCloud Drive?

The purpose of iCloud Drive is to sync and store files across Apple devices. This feature allows users to access their documents, photos, and other files from any device that is connected to their iCloud account, including iPhones, iPads, Macs, and even PCs. iCloud Drive facilitates file sharing and collaboration, ensuring that the most current versions of files are available regardless of which device is being used.

Unlike the other choices, which are very specific or limited in scope, iCloud Drive provides a comprehensive solution for file management and accessibility, allowing users to store a wide variety of file types, not just music or device settings. It enhances the continuity of work and storage across all Apple devices, making it a vital part of the Apple ecosystem.
