C Correct answer
Explanation

The mouse is a pointing device that allows users to navigate graphical user interfaces (GUIs) without typing commands on a keyboard. By using a cursor to select icons and menus, the mouse significantly reduces the need for keyboard input for basic navigation. Joysticks and light pens are also input devices, but the mouse is the primary tool that replaced keyboard-only operation.
