The correct answer is: D. Touch screen kiosks
Touch screen kiosks are interactive digital displays that are typically used in public places to provide information, such as directions, maps, or product listings. They can also be used to accept payments, collect feedback, or provide customer service.
Monitors are electronic visual display devices that are typically used to display computer output. They can also be used to display television or other video signals.
Overhead projectors are devices that project an image from a transparency onto a screen or wall. They are typically used in classrooms or presentations to display images or text.
A combination of monitors and overhead projection is sometimes used to display information at public places. For example, a monitor may be used to display a map of a building, and an overhead projector may be used to display a list of events or activities.
However, touch screen kiosks are the most common type of device used for displaying information at public places. They are easy to use, can be updated easily, and can provide a more interactive experience for users.
