Kepler's third law of motion relates the period of revolution of a planet to its average distance from the sun. The correct variables to understand Kepler's third law are:
**period of revolution, distance to sun**.
However, since this exact phrasing isn't in your options, the closest correct choice would be:
**orbital velocity, distance to sun.**
Kepler's third law states that the square of the orbital period (time taken for one complete orbit) is directly proportional to the cube of the semi-major axis of its orbit (average distance from the sun).
**period of revolution, distance to sun**.
