The correct answer is B) Printer.

In the given list, Scanner, Mouse, and Keyboard are all input devices used to provide data or commands to a computer. A Printer, on the other hand, is an output device that produces hard copies of data processed by the computer.

Input devices translate information from the outside world into a form that the computer can understand. Output devices translate information from the computer into a form that humans can understand or use (like printing on paper, displaying on a screen, or sound). The printer is the only output device in the list, making it the odd one out.
