Which of the following provides a user-friendly interface?

Correct answer: GUI. A GUI (Graphical User Interface) lets users interact using windows, icons, menus, and buttons.

• OS: An operating system manages the computer and may offer a graphical or a command-line interface.
• MacOS: MacOS is a specific operating system that uses a GUI, not the type of interface itself.
• All of the above: “All of the above” is incorrect because GUI is the only option that names a type of interface.
