System Software
System software is designed to control the operations of a computer. It acts as an intermediary between the hardware and the application software. It provides a platform for running application programs and manages the resources of the computer system.

Application Software
Application software refers to programs that are designed to perform specific tasks or solve specific problems for users. It includes word processors, spreadsheets, databases, web browsers, and other software applications that users interact with directly. While application software is an important part of a computer system, it is not designed to control the operations of the computer itself.

Utility Software
Utility software refers to programs that provide additional functionality to the computer system. It includes tools for managing and optimizing system performance, disk cleanup and defragmentation, data backup and recovery, antivirus and firewall protection, and other system maintenance tasks. While utility software is useful for managing and maintaining the computer system, it does not control the operations of the computer.

User
The user is an individual who interacts with the computer system. Users can run application software, access system software, and utilize utility software to perform tasks and achieve their goals. However, the user does not control the operations of the computer itself.

Conclusion
Out of the given options, system software is designed to control the operations of a computer. It provides a platform for running application software and manages the resources of the computer system. Application software, utility software, and the user play important roles in the functioning of a computer system, but they do not control the operations of the computer itself.

Software is basically classified into two: System and application. System Software is designed to control the operations and extend the processing capability of a computer system.
