The examples of pointing devices among the options given are:
A pointing device is a computer peripheral that is used to input data into a computer screen by signaling a position in a multidimensional space. The mouse is the most common pointing device and it lets you move a cursor around the computer screen to make selections and move items. A touchpad, also known as a trackpad, is a specialized surface that can detect the motion and position of a user's finger or stylus, typically used on laptops. A keyboard is not considered a pointing device because it's primarily used for typing, not pointing. A scanner is an input device that converts paper documents and photos into digital data, but it isn't used for controlling or interacting with the computer's graphical user interface.
