Answer:
C. Circumcenter.
Explanation:
We have been given an image of a triangle KLM and we are asked to choose the term that describes point N.
We can see that point N is the point where perpendicular bisector of our given triangle are intersecting.
Since the point where the perpendicular bisectors of a triangle intersect is called circumcenter, therefore, point N is the circumcenter of our given triangle KLM nad option C is the correct choice.
