The problem asks for the location of the circumcenter of triangle $\Delta ABC$. The circumcenter is the point where the perpendicular bisectors of the sides of a triangle meet. It is also the center of the circumcircle, which is the circle that passes through all three vertices of the triangle.

Let's analyze the points shown in the diagram:

• Point $D$ lies at the intersection of the perpendicular bisectors of the triangle's sides.
• Point $F$ appears to be on one of the triangle's sides but does not coincide with the perpendicular bisectors.
• Point $E$ is also on the triangle but is not at the intersection of the bisectors.

Since the circumcenter is the point where all the perpendicular bisectors intersect, the correct answer is Point D.

Do you want further clarification on the circumcenter, or any other details about the geometry involved?

Tip: The circumcenter can lie inside, on, or outside the triangle depending on whether the triangle is acute, right, or obtuse.
