It can be seen in the figure that the plane is perpendicular to the base and the top of the elliptical cylinder, therefore the shape formed must have a straight line in its lower and upper sides; this discards shapes 1 and 4. Also, this perpendicularity makes parallel the left and the right side of the shape formed, dicarding shape 2.
