Explanation:

Comets are near-Earth objects composed mostly of ice, dust, and rocky material, and they have very long, variable orbital periods (ranging from a few years to tens of thousands of years). Asteroids are rocky/metallic with shorter orbital periods, while meteors/meteorites are related to small objects entering Earth's atmosphere, not defined by ice composition and long orbits.

B. a comet
