Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: A GUI involves the use of windows and menus, and takes up a lot of memory and resources.

Reason R: In order to use a GUI, users have to learn a list of system commands.

In the light of the above statements, choose the correct answer from the options given below:

Correct answer: C

CONCEPT

A graphical user interface (GUI) lets a user interact through visual controls such as windows, icons and menus. A command-line interface (CLI), by contrast, relies on typed commands and their syntax.

Graphical controls generally need additional memory and processing resources to draw and manage them. Memorising a list of system commands is characteristic of a CLI, not a requirement for ordinary GUI use.

APPLICATION

  1. Classify Assertion A: it links a GUI with windows and menus and notes its greater resource overhead. Both features are standard characteristics of a GUI, so A is true.

  2. Classify Reason R: a GUI is designed around visible controls and direct manipulation; learning a list of typed system commands is a CLI requirement. Therefore R is false.

  3. Because R is false, it cannot explain A.

CONTRAST

  • “Both A and R are true and R is the correct explanation of A” fails because command memorisation does not describe normal GUI operation.

  • “Both A and R are true but R is not the correct explanation of A” still incorrectly treats the command-memorisation statement as true for a GUI.

  • “A is true but R is false” matches the independent classification of the two statements.

  • “A is false but R is true” reverses both classifications.

CROSS-CHECK

A user can select a visible menu item in a GUI without recalling a command name, while the visual environment still consumes resources to render and manage its controls. This confirms that A is true and R is false.

Result: A is true but R is false.
