You have not provided the options, therefore, I can not provide an exact answer.
However, I will help you with the concept
In a triangle, the circumcenter is defined as the point of intersection of the three perpendicular bisectors in the triangle
The circumcenter is characterized by the following:
1- The circumcenter is the center point of the circumcircle
2- The circumcenter is equidistant from the three vertices of the triangle
3- Position of circumcenter:
in acute triangle ........> it lies inside the triangle
in right-angles triangle .......> it lies at the midpoint of the hypotenuse
in obtuse triangle ..........> it lies outside the triangle
Hope this helps :)
