Which is the correct example of the input-processing-output sequence?

Correct answer: Entering numbers by keyboard, processing them in the CPU, and displaying the result on the monitor

The input-process-output model explains the basic working cycle of a computer. First, an input device such as a keyboard supplies data; next, the CPU processes or calculates it; finally, an output device such as a monitor presents the result. Option A follows this order. The other choices assign impossible functions to monitors, mice, printers, keyboards, speakers, or scanners.
