Discussion
Identify the wrong match for output devices used for specific purposes.
Answer: C
The wrong match is Projector, Sound card, MICR.
MICR (Magnetic Ink Character Recognition) is an input device. Banks use it to read the magnetic-ink numbers printed along the bottom of cheques, so it does not belong in a list of output devices.
The other three sets contain only output devices, or the cards that drive them: a projector shows the screen image, speakers produce sound, and the sound card and video card convert the computer's data into audio and video output.
