The asteroid belt is a vast region of space in our Solar System, stretching out between the orbits of Mars and Jupiter. It is estimated to contain millions of small celestial objects, mostly rocky debris left over from the formation of the Solar System. Option A is incorrect because Earth is located closer to the Sun than Mars, so the asteroid belt cannot be between Earth and Mars. Option C is incorrect because Jupiter is located before Saturn, so the asteroid belt cannot be between Jupiter and Saturn. Option D is incorrect because the asteroid belt is located within our Solar System, which is defined as the collection of planets, moons, and smaller objects that orbit around our Sun. Therefore, the only correct and logical option is B, between Mars and Jupiter.
