For using GUI, which statement is true?

• A. It uses less memory than CLI
• B. It prevents multitasking by isolating windows
• C. Visual representation makes it easier for beginners who don’t know commands
• D. It makes command-line input mandatory

Answer: (C)

Graphical user interfaces present information visually and interactively, which helps beginners recognize icons, menus, and windows without memorizing text commands. This visual approach lowers the barrier to performing tasks, making it easier to learn how to use the system.

The other statements aren’t accurate. GUIs typically use more memory than a plain command-line interface, not less. They don’t inherently prevent multitasking; in fact, they enable multitasking by letting you work with multiple windows and applications at once. And while GUIs can include a command line as an optional feature, they do not make command-line input mandatory.
