The correct answer is (d) Mars
The best explanation: By observing the motion of Mars in the sky, Kepler inferred that the planets have elliptical orbits around the sun. Kepler discovered that a simple ellipse would clearly define the orbit of Mars and eliminate many complexities. It would also eliminate the need for epicycles.
