The answer is C. Circle.
A triangle, rectangle, and square are all polygons. A polygon is a closed figure with straight sides. A triangle has three sides, a rectangle has four sides, and a square has four sides and four equal sides. A circle is a round figure with no sides.
A circle is the only shape that is not a polygon.
