Which statement describes a disadvantage of Graphical User Interfaces?

• A. Is not user-friendly.
• B. Only runs on high-end devices.
• C. Requires a large amount of memory.
• D. Lacks color.

Answer: (C)

Graphical User Interfaces require more memory because they must store and render many graphical elements—windows, icons, fonts, images, and the controls users interact with. The windowing system and the rendering pipeline keep track of how things look and where they appear, which uses RAM. That extra resource use is a drawback, especially on devices with limited memory, where performance can be affected. The other statements don’t describe a general drawback of GUIs: they are designed to be user-friendly, they can run on a wide range of devices (not only high-end ones), and they use color as a standard part of the interface. So the main disadvantage described is the need for a large amount of memory.
