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.
One big circle as face. Two small circles as eyes.

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.
