The correct answer is:
E) A regular hexagon.
Explanation:
The point marked on the circle will serve as the first vertex. From this vertex, Stella will measure the radius using her compass (from this vertex to the center). She then turns the compass around and marks an arc on the circle. This will be the second vertex of the polygon.
Keeping the compass the same width, she moves it to the arc she just constructed and constructs another arc. This will be the third vertex.
She does this another 3 times. This makes the other 3 vertices, for a total of 6.
Since there are 6 vertices, this is a regular hexagon.
