Quizplus · Accepted Answer

The synodic period is the time it takes for a planet to return to the same position in the sky relative to the Sun and Earth. This period is directly related to the planet's orbital period and the relative positions of the planets along their respective orbits. Uranus has the longest orbital period of the three planets, so its synodic period will be the longest as well. Jupiter has the shortest orbital period, so its synodic period will be the shortest. Therefore, the order from shortest to longest synodic periods is Uranus, Saturn, and Jupiter, making choice B the correct answer.
