To answer this question, let's go through each option to understand why it is correct or incorrect:

A. Online help - Online help is a feature of a GUI that provides users with assistance and guidance on how to use the program. It enhances the user's learning experience by providing access to resources such as tutorials, FAQs, and user manuals. This feature makes learning a program easier for users.

B. WYSIWYG formatting - WYSIWYG (What You See Is What You Get) formatting allows users to see the final appearance of their document or design as they create it. This feature makes it easier for users to understand how the program works and enables them to make real-time adjustments. It enhances the user's learning experience.

C. Dialog boxes - Dialog boxes are windows that appear on the screen and prompt the user to enter information, make selections, or perform specific actions. They provide a clear and organized way for users to interact with a program. Dialog boxes make learning a program easier by presenting options and guiding users through different tasks.

D. Detailed key strokes and commands - This option is correct because detailed key strokes and commands are not a feature of a GUI that makes learning a program easy for users. GUIs are designed to provide a visual and intuitive interface, reducing the reliance on complex keyboard shortcuts and commands. Instead, GUIs rely on graphical elements such as icons, menus, and buttons to perform tasks.

E. Icons - Icons are graphical representations that represent specific functions or actions within a program. They provide a visual cue for users to understand the purpose and functionality of different features. Icons make learning a program easier by providing a visual reference and enabling users to quickly identify and access different functions.

The correct answer is D. Detailed key strokes and commands. This option is not a feature of a GUI that makes learning a program easy for users, as GUIs aim to minimize the need for complex keyboard shortcuts and commands by providing a visual and intuitive interface.
