14. A user can make any change in the image using

  1. Non-Interactive computer graphics
  2. Interactive computer graphics
  3. Both (A) and (B)
  4. None of the above

Answer : B
Explanation: A user can make any change in the image using only Interactive computer graphics as in interactive Computer Graphics, the user has some control over the picture, it means that the user can make any change in the produced image. One example of it is the ping-pong game.
