If an Asteroid Were Found to Be Orbiting in a Circular

If an asteroid were found to be orbiting in a circular path around the Sun at the same distance as Jupiter (5.2 au) , what would be its orbital period compared with that of Jupiter, which is 11.86 years?

A) about 10 times as long as Jupiter's period, or 118.6 years, because the Sun's gravitational force is much smaller on such a small object
B) about 1/10 of Jupiter's period because it is a much smaller object
C) same as Jupiter's period, 11.86 years
D) exactly 1/2 of Jupiter's period, or 5.93 years, because it would be in a synchronous orbit with Jupiter
