The shape that has the same distance between its center and any point on its outline is a circle.

To understand this concept, let's break it down:

A triangle has three sides, so the distances from its center to the different vertices will vary.

An octagon also has multiple sides, so the distances from its center to the various points on its outline will differ.

A square, although having equal side lengths, does not have the same distance from its center to any point on its outline.

However, a circle is defined as a set of points that are equidistant from a fixed point called the center. This means that regardless of which point you choose on the outline of a circle, the distance from that point to the center will always be the same.

Therefore, the correct answer is c. Circle.
