Detailed explanation-1: -Asteroids are small, rocky objects that orbit the Sun. They are a lookalike of the planets, but smaller and often irregularly shaped. Mostly they are composed of a variety of rocks, but some have clays or metal.
Detailed explanation-2: -A planet is round because of gravity. A planet’s gravity pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circle.
Detailed explanation-3: -(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.
