An application has a frame that uses a Border layout manager. Why is it probably not a good idea to put a vertical scroll bar at North in the frame?
A) The scroll bar’s height would be its preferred height, which is not likely to be enough.B) The scroll bar’s width would be the entire width of the frame, which would be much wider than necessary.C) Both a and b.D) Neither a nor b. There is no problem with the layout as described.
