What does an operating system provide so you can interact with a device?

A) graphical user interface
B) file storage
C) flash drive
D) platform

An operating system provides a graphical user interface (GUI) that allows users to interact with a device by using visual elements such as icons, menus, and windows. The GUI makes it easier for users to access and manage programs, files, and settings on the device. File storage and flash drives are related to storage and data transfer, but they are not the main functions of an operating system. A platform is a general term that may refer to a hardware or software environment that supports the operation of an application, but it is not specific to operating systems.
