    Option A and D contains same answer. Both options are incorrect

    Operating systems provide both command line as well as graphical user interfaces

    Explanation:

    An immersive graphical component system for computer software is a graphical user GUI. A GUI is seen as more simple than a graphical unit-line interface, like MS-DOS or a Unix-like operating system shell.

    In a GUI, commands like opening, deletion and moving files are executed using a window, an icon and menu. While a mainly mouse-based GuI operating system is used, a keyboard can also be used through keyboard shortcuts or arrow keys.

    For example, you would move the mouse cursor to the icon of the program and double click on it to open a program on a GUI system.
