Answer: The correct answer is option c.
Step-by-step explanation:
Kepler's law of planetary motion:
- The the planets orbits around the sun is elliptical path, with sun at one focus.
- A line drawn from the center of the planet to the center of sun will sweep out equal areas in equal intervals of a time.
- the ratio of the square of the period of any planet is equal to the ratio of the cubes of their average distance from the sun.
From the above laws the correct options is elliptical.
Hence, the correct answer is option c.
