Detailed explanation-1: -(C) Asteroids changes into comet when they come near to the sun. This option is not correct. Asteroids are small, rock type object that orbits around the sun, just like planets but they are not considered as planets because they are very small in comparison.
Detailed explanation-2: -Asteroids are rocky, airless worlds that orbit our sun, but are too small to be called planets.
Detailed explanation-3: -Instinctively, a planet is a large body, orbiting around the sun (or more generally around a star), in the plane of the ecliptic. Large objects are planets, small bodies are asteroids. Planets are confined to this plane, while asteroids can have quite high inclinations compared to this plane.
Detailed explanation-4: -Why didn’t a planet form where the asteroid belt is now located? The asteroid belt didn’t become a planet because it’s positioned too close to Jupiter. The gas giant’s immense gravitational influence prevented the asteroids from collecting together into one large body.
