Compare GUI and CLI interfaces in terms of usability and accessibility.

• A. CLI is visual and intuitive; GUI is powerful and scriptable; accessibility depends on design and screen reader compatibility.
• B. GUI is visual and intuitive; CLI is powerful and scriptable; accessibility depends on design and screen reader compatibility.
• C. GUI is text-based; CLI is graphical; accessibility only for GUI.
• D. CLI cannot be used for automation; GUI supports macros by default.

Answer: (B)

Usability and accessibility differ in that graphical user interfaces present information visually with windows, icons, and menus, which makes tasks easy to learn and perform by pointing and clicking. Command-line interfaces rely on typed commands, options, and scripting, offering immense power and automation potential for managing complex tasks and workflows. Accessibility depends on how each interface is designed: GUI accessibility improves with features like screen readers, keyboard navigation, and adjustable contrast, while CLI accessibility hinges on clear prompts, consistent behavior, and good screen reader support. This combination—GUI being visual and intuitive, CLI being powerful and scriptable, with accessibility shaped by design—best captures how these interfaces differ. The other options mix up these roles or make incorrect assumptions about automation and graphical capabilities.
