Which of the devices below is an input device? ?

Err I don't see an image or anything so I'm not sure what you're referring to, but examples of input devices would be a keyboard, mouse, (drawing/graphic) tablet - they are inputting data into the system

versus output devices such as the monitor which is displaying data

Inputs are things you have plugged in and makes operations non-visible to the eye. Output devices are things like the computer monitor which displays you the image data to your eyes.
