located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets.
Explanation: In the given image, the asteroid belt lies in the B position i.e. between the orbits of Mars and Jupiter.
Asteroid belts contains infinite number of asteroids, that ranges in size from a few meter to hundreds of kilometers. They normally moves at a speed of about 80,000 km/hr and continuous collision between them takes place. Some of them even have satellites and most of them that are found to exist on earth are derived actually from that asteroid belt.
