Which device can perform both input and output functions?

Answer and explanation

Correct answer: Touchscreen

A touchscreen performs both output and input functions. Its display produces visual output, while its touch-sensitive surface detects taps, swipes, and other commands as input. A basic printer mainly outputs printed information, speakers output sound, and a microphone mainly accepts sound input. Because the touchscreen combines display and touch detection in one device, option C is the only complete answer.
