The correct option is C. File management. Detailed Explanation 1. Understanding System Software: System software is a type of software designed to provide a platform for other software. It acts as a mediator between the hardware and the user applications. The primary role of system software is to manage the hardware components of a computer and provide a user interface for interaction. 2. Major Functions of System Software: Among the various functions of system software, file management is one of the most critical. File management involves the organization, storage, retrieval, naming, sharing, and protection of files on a computer system. This function is essential for users to efficiently access and manage their data. 3. Why Option C is Correct: - File Management: System software, particularly operating systems (like Windows, macOS, Linux), provides tools and utilities for file management. This includes creating, deleting, moving, copying, and organizing files and directories. The operating system ensures that files are stored in a way that they can be easily accessed and managed by users and applications. - User Interaction: Through file management, users can navigate their file systems, find documents, and manage their data effectively. This is a fundamental aspect of how users interact with their computers. Why the Other Options are Incorrect: A. Collection of Files: - This option is vague and does not accurately describe a function of system software. While system software does involve managing collections of files, simply stating "collection of files" does not encompass the broader and more critical functions of organization, retrieval, and management that system software provides. B. Translation of machine language into machine code: - This option is misleading. Machine language and machine code are often used interchangeably, as machine code is the binary representation of machine language instructions. System software does not translate machine language into machine code; rather, it executes machine code directly. The translation of high-level programming languages into machine code is typically the role of compilers or interpreters, which are not classified as system software. D. Arrangement of files in ascending order: - While arranging files can be a part of file management, it is a very specific and limited function. File management encompasses much more than just sorting files; it includes creating, deleting, and organizing files and directories, as well as managing permissions and access rights. Therefore, this option does not capture the full scope of what system software does. Summary of Key Points:

• System software primarily manages hardware and provides a platform for applications.
• File management is a major function of system software, involving the organization, storage, and retrieval of files.
• Other options either misrepresent the functions of system software or are too narrow in scope.
• Understanding the role of system software is crucial for effective computer usage and data management.

By focusing on the comprehensive role of file management within system software, you can better appreciate how operating systems facilitate user interaction with computer systems.
