D.  The orbit is oval-shaped.

Explanation:

The word "elliptical" means any shape or direction that has an ellipsis/ oval shape or appearance. This means that anything that moves in an oval shaped pattern or anything that is in an oval shape, is elliptical.

The earth's orbit that revolves around the sun is moving in such a way that it resembles an oval direction/ shape in its movement. The shape taken or made by the shape of the movement is oval, which means that it is moving in an oval shaped pattern.  

Thus, the correct answer is option D.
