Which organization was inspired by Englebright to create a graphical user interface?

The correct choice is C, Xerox PARC, because it was at Xerox Palo Alto Research Center (PARC) where the modern graphical user interface (GUI) was first developed. This innovation was a key advancement in human-computer interaction, stemming from work done by researchers like Alan Kay, who was inspired by the ideas of Doug Engelbart. Engelbart’s work included early concepts of a user-friendly interface that utilized windows, icons, and pointing devices, which laid the foundation for subsequent developments.

Xerox PARC experimented with these ideas and ultimately created the first commercial implementation of a GUI. Their work influenced many later developments in personal computing, making a significant mark on how users interact with computers today. Other companies, including Apple, IBM, and Microsoft, did adopt and build upon these ideas later but were not the original creators inspired by Engelbart’s concepts; thus, they do not hold the same foundational significance in this context.
