Attempt This Question
Not attemptedCorrect Answer: (c) I and II are correct
Statements I and II are correct: asteroids are rocky solar-orbiting debris and while most are small, bodies like Ceres reach ~1000 km diameter. Statement III is wrong because the main asteroid belt lies between Mars and Jupiter, not Jupiter and Saturn; hence only I and II hold.
