What is the main function of the input unit in a computer system?

Answer and explanation

Correct answer: Receiving data and instructions

The governing concept is the input-process-output cycle. The input unit receives raw data and instructions from a user or an input device, such as a keyboard, mouse, or scanner, and passes them to the computer for processing. Printing results belongs to the output unit, permanent file storage belongs to secondary storage, and supplying electricity is the power supply's role. Therefore, option A is correct.
