Which statement best reflects the role of the CPU in a computer system?

The CPU, or Central Processing Unit, is often referred to as the brain of the computer because it is primarily responsible for processing data and executing instructions. When the statement mentions that the CPU manipulates data to produce information, it accurately captures this crucial function. The CPU retrieves data from memory, processes it according to a set of instructions (which can be coming from programs or applications), and then generates output information that can be used by the system or presented to the user. This process involves arithmetic calculations, logic operations, and control tasks that enable the computer to perform a wide range of functions.

While other components of the computer system do have important roles—such as storing files and applications (storage devices), connecting hardware (motherboard and peripheral connections), and providing a user interface (software and operating system)—none of these functions accurately describes the primary role of the CPU. The statement clearly highlights the CPU's primary purpose, making it the best reflection of its role in a computer system.
