Means that the interface only allows for the entry of commands without personalization features.

• A. Graphical User Interface
• B. Command-Line Interface
• C. Structured programming
• D. Loop structure

Answer: (B)

A command-line interface is a text-based way to interact with a computer, where users type commands to perform tasks and there are typically no built-in graphical controls or personalization features. This aligns with the statement because the interface described allows only command entry and lacks the graphical elements or customization options you’d expect in a GUI.

The other options describe programming concepts rather than how a user interacts with a system. Graphical User Interface refers to visual elements like windows, icons, and menus and often includes personalization options such as themes and layout choices. Structured programming is about organizing code into well-structured blocks to improve clarity and maintainability. A loop structure is a control flow construct that repeats actions, a concept within programming rather than an interface type.
