That is a very small circle, probably 15 pixel diameter.
Gimp is a pixel editor. So the selection follows the pixel boundaries. That is why it is jagged.
You don't say what you want to do with the circle. One thing that can be done is stroke the circle.
One way is just to use Edit > Stroke Selection
Or you can first convert the selection to a path Select > To Path The path is not initially visible, so go the Path Dialogue and click on the eye to make the path visible. Then Edit > Stroke Path
Another way is to make the selection bigger. On a 200 pixel diameter circle the jagged edges are barely noticeable.
