Answer:
Kn
Step-by-step explanation:
Kn is not a correct name for the line given in the diagram as line segment is bounded by the two different points, it includes the both end points.
In the given figure, point "n" is outside the arrows and thus cannot be joined with K in order to form a line. Whereas, IJ, KJ and KI are the correct lines as they are lying inside the arrows and are joined together to form a line.
