Correct Answer: A
Detailed Solution
The CPU is commonly called the brain of a computer because it processes instructions and controls and coordinates the functions of different components of the computer.
The CPU performs processing mainly with the help of the Arithmetic Logic Unit (ALU), Control Unit (CU), and registers/internal storage.
The ALU performs arithmetic calculations and logical operations, while the Control Unit controls the execution of instructions and the flow of data among different units.
In contrast, a Keyboard is an input device, a Disc is a storage medium/device, and a Printer is an output device.
