Answer:
A. Circumcenter
Explanation:
Circumcenter of a triangle is the point in plane that is equidistant from the 3 vertices of the triangle.It is located by finding the point of intersection formed by the perpendicular bisectors of each of the sides of the triangle.
This point identifies the midpoint of the triangle.By finding the midpoints of the segments/sides of the triangle then drawing perpendicular lines through the points the circumcenter is the point of intersection of the bisectors.
