Which statement about interfaces is most accurate for automation purposes?

• A. Command-line interface is powerful and scriptable for automation.
• B. Graphical interfaces are more scriptable.
• C. Only GUI supports automation.
• D. CLI cannot run scripts.

Answer: (A)

Interfaces that support automation work best when you can control them with code and reuse those steps. A command-line interface fits this use because you can write scripts that run multiple commands in sequence, pass parameters, redirect input and output, and loop or conditionally execute tasks. This makes repetitive work reliable and easy to reproduce in different environments. Graphical interfaces can be automated, but it’s usually more fragile and requires extra tools to simulate mouse clicks and keystrokes, which can break with small UI changes. The idea that only graphical interfaces support automation isn’t accurate, and the notion that the CLI cannot run scripts is simply incorrect. So, the statement that a command-line interface is powerful and scriptable for automation is the best description.
