A) Protection and security: Managing user access, permissions, and resource protection. This is a fundamental OS function.
C) Device management: Managing hardware devices through drivers, controlling I/O operations. This is a fundamental OS function.
D) File management: Organizing and managing files and directories on storage devices, providing a file system. This is a fundamental OS function.
B) Store and handle data: While the OS provides the infrastructure (like file systems and memory management) for data to be stored and accessed by applications, the primary function of storing, manipulating, and interpreting the *content* of data belongs to application programs (like databases, word processors, etc.), not the core OS itself. The OS manages *how* data is stored and accessed on physical media, but not the *data itself* in the sense of its content or meaning. Therefore, “Store and handle data” is not typically listed as a distinct primary function of an operating system compared to the others.
