Massachusetts Institute of Technology in 1963
Imperial college of Science and Technology, London, 1973
University of Aston, Birmingham, 1960
Cranfield Institute of Technology, London, 1962 E. None of the above

The correct answer is: A. Massachusetts Institute of Technology in 1963.

SKETCHPAD was a computer graphics system developed by Ivan Sutherland at the Massachusetts Institute of Technology (MIT) in the 1960s. It was one of the first systems to allow users to interact with a computer graphically, and it had a major impact on the development of computer graphics.

SKETCHPAD was demonstrated at the MIT Lincoln Laboratory in 1963. It was a revolutionary system that allowed users to draw and manipulate objects on a computer screen using a light pen. This was a major advance over previous systems, which required users to enter commands using a keyboard or a teletypewriter.

SKETCHPAD was also one of the first systems to use a graphical user interface (GUI). A GUI is a type of user interface that uses icons, windows, and menus to interact with the user. GUIs are now the standard way to interact with computers, but they were first developed for SKETCHPAD.

SKETCHPAD was a major breakthrough in the development of computer graphics. It showed that it was possible to create interactive, graphical user interfaces for computers. This work had a major impact on the development of computer graphics, and it continues to be used today.

The other options are incorrect because they do not correspond to the correct year or location of the development of SKETCHPAD.
