Graphical pictures that represent an object like file, folder etc are:

Task bar
Windows
Icons
Desktop E. None of these

The correct answer is C. Icons.

Icons are graphical pictures that represent an object like file, folder, etc. They are usually small and can be placed on the desktop or in a folder. To open an icon, double-click on it.

A taskbar is a horizontal bar at the bottom of the screen that contains buttons for open programs and other shortcuts.

A window is a rectangular area on the screen that contains a program or document.

A desktop is the background of the screen where icons and windows are displayed.

E is not the correct answer because it is not a graphical picture that represents an object like file, folder, etc.
