The correct answer is (c) Kepler's Third Law.
Kepler's Third Law of Planetary Motion, also known as the Law of Harmonies, states that the square of the orbital period (T²) of a planet is directly proportional to the cube of the semi-major axis of its orbit (R³). This relationship can be expressed as T² ∝ R³, which means that the ratio of the square of the orbital period to the cube of the distance from the sun is constant for all planets in the solar system.
