The answer is B. A meteorite enters the earth's atmosphere while a comet don't. A comet is a small body that orbits the sun. It does not enter the Earth's atmosphere however it can stay close to the sun displaying a visible coma, a thin atmosphere around the comet. On the other hand, a meteorite is a meteoroid that survives entering the Earth's atmosphere. It is a small particle of debris in the solar system.
