Explanation:

The question asks for a type of program that makes a computer easy to use. This implies software designed to enhance the user experience by simplifying management, maintenance, or optimization tasks. Option (c) Utility: Utility software is a type of system software designed to help analyze, configure, optimize, or maintain a computer. Its primary purpose is to assist in the management and maintenance of the computer system, thereby making the computer *easier to use* for the end-user by improving its performance, ensuring its security, and facilitating various system-level tasks. For instance, disk defragmenters optimize hard drive performance, antivirus programs protect against malware, and file compression utilities help manage storage space. These tools directly contribute to a smoother, more efficient, and user-friendly computing experience. Without utility software, users would have to manually perform complex system tasks, making the computer much harder to manage and operate effectively. Therefore, utility programs are specifically crafted to simplify and enhance the overall usability and health of a computer system, directly addressing the 'make easy to use a computer' aspect. Option (a) Operating system: An operating system (OS) is the most fundamental type of system software that manages computer hardware and software resources and provides common services for computer programs. While an OS makes a computer *functional* and *possible to use*, its core role is to provide the foundational environment, not necessarily to 'make it easy to use' in the sense of adding convenience features or maintenance tools beyond basic operation. For example, a command-line interface OS might be functional but not inherently 'easy to use' for a novice. Ease of use, in the context of specific tasks or system maintenance, is often enhanced by application or utility software built *on top* of the OS. Thus, while essential for a computer's operation, it doesn't primarily focus on making the *act* of using the computer easy in the way utility software does. Option (b) Application: Application software (or an application) is a computer program designed to perform a specific task or set of tasks for the end-user. Examples include word processors, web browsers, video players, and games. These programs make it easy to *do specific things* with a computer (e.g., write a document, browse the internet), but they don't inherently make the *computer itself* easier to use or manage as a whole system. An application solves a user's problem or fulfills a user's need, but it doesn't typically optimize system performance or provide system maintenance, which are the functions that generally 'make a computer easy to use' from a system management perspective. Option (d) Network: A network is a collection of interconnected computers and devices that can share resources and data. It is a physical and logical infrastructure, not a program. While networking allows computers to be more versatile and share resources, it is not a 'program' that makes a computer easy to use. Instead, it's a connectivity infrastructure. Software *enables* networking, but a network itself is not a program. Therefore, this option is fundamentally incorrect as it misidentifies a concept as a program. Option (e) None of these: This option would be correct only if none of the other options accurately described a program that makes a computer easy to use. However, as established, utility software directly fulfills this description by providing tools for system optimization, maintenance, and security, all of which contribute significantly to a user-friendly computing experience. Therefore, a correct answer is present among the given choices, rendering 'None of these' incorrect.
