Laser Jet E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: A. VDT
A VDT (Visual Display Terminal) is a combination input-output device because it allows users to input data (e.g., by typing on the keyboard) and view output (e.g., text or images on the screen).
A keyboard is an input device that allows users to enter text into a computer.
A printer is an output device that allows users to print text or images from a computer.
A laser jet is a type of printer that uses a laser to create an image on a drum, which is then transferred to paper.
None of the above options are combination input-output devices.
