Which planet is considered as the Dwarf planet?

Answer: Option C

Pluto is considered as a dwarf planet. This is called so because it has not cleared its neighbourhood around its orbit. International Astronomic Unit declared it a Dwarf Panet in 2006. It orbits in a disc-like zone beyond the orbit of Neptune called the Kuiper belt, a distant region populated with frozen bodies left over from the solar system's formation.
