Q. Let R be the rectangular window against which the lines are to be clipped using 2D Sutherland-Cohen line clipping algorithm. The rectangular window has lower left-hand corner at (-5,1) and upper right-hand corner at (3,7). Consider the following three lines for clipping with the given end point co-ordinates:

Line AB: A(-6,2) and B(-1,8)
Line CD: C(-1,5) and D(4,8)
Line EF: E(-2,3) and F(1,2)

Which of the following line(s) is/are candidate for clipping?
