Statement I is correct because asteroids are indeed rocky, metallic remnants left over from the early formation of the solar system that orbit the Sun. Statement II is correct because while most asteroids are small, some are very large. For example, Ceres, the largest object in the asteroid belt, has a diameter of approximately 940 km, which is nearly 1000 km. Statement III is incorrect because the main asteroid belt is located between the orbits of Mars and Jupiter, not between Jupiter and Saturn. Since statements I and II are true and statement III is false, the correct option is C.
