Which of the following is a small graphical representation of a computer application on the desktop? 

Explanation / व्याख्या:

An Icon is a small graphical representation of a program, file, folder, or application displayed on the desktop. It helps users easily identify and open applications by simply double-clicking on it.

For example:
