To determine which of the given options is a list of input devices, we need to understand what input devices are.

Input devices are hardware devices that allow users to input data into a computer system. These devices enable users to interact with the computer and provide information or commands for processing.

Let's analyze the given options:

A. Printer, mouse, speakers - Out of these three, only the mouse can be considered an input device. Both printer and speakers are output devices.

B. RAM, monitor, printer - RAM is not an input device; it is a type of memory used by the computer. Monitor and printer are output devices.

C. Microphone, mouse, scanner - Both the microphone and scanner are input devices that allow users to input audio and scanned documents, respectively. The mouse is also an input device.

D. CPU, monitor, operating system - Out of these three, only the monitor is not an input device. The CPU is the central processing unit that performs calculations and processes data, and the operating system is software that manages computer hardware and software resources.

Based on the above analysis, the correct option is:

C. Microphone, mouse, scanner

These three devices are all input devices that allow users to provide input to a computer system.
