Each face of a cube is shaped like a square. The sides of each face are called edges. A cube has 12 edges.

A sphere is a geometrical object in three-dimensional space that is the surface of a ball. Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point in a three-dimensional space.
Examples of sphere include: Ball. Planets. Moon.

Option D shows a pair of a rectangle because :
⇒ The figures has four sides.
⇒ Opposite sides are parallel, congruent and equal.
⇒ And all four angles are 90^∘
⇒ So, option D justify the all properties of rectangle and other options don't then option D is a right option.

It has three sides.

By observing the figure it can be clearly said that the following figure have 8 edges.

Cube has 6 faces

Option C. The figure contains exactly three circles.

Only 'D' is closed figure.

All other are made up of lines.

The dotted line  divides the figure of option D in  2 equal parts, while the other options are not divided symmetrically
∴ Correct answer is option D.
