Planets move in elliptical . . . . . . round the sun.

figures
orbits
shapes
circles

The correct answer is: B. orbits

Planets move in elliptical orbits around the sun. An ellipse is a shape that is similar to a circle, but with two points that are closer together than the other two points. The sun is located at one of the two closer points, and the planet’s orbit takes it around the sun in a path that is shaped like an ellipse.

The other options are incorrect because they do not accurately describe the shape of a planet’s orbit. A figure is a general term for any shape, but it does not specifically refer to an ellipse. A shape is a general term for the outline of something, but it does not specifically refer to an ellipse. A circle is a shape that is round, but planets do not move in circular orbits around the sun.
