Solution
The correct option is D Pluto
General Assembly of the International Astronomical Union (IAU) held on August 24, 2006, laid the ground rules for a celestial object to be qualified as a planet.
The object has to be in an orbit around the sun. The object should have sufficient gravity to pull itself into a spherical, or nearly spherical, shape. The object should have ‘cleared the neighbourhood’ of its orbit.
Although the first two conditions are satisfied by Pluto, but it does not satisfy the third condition. Thus, pluto is not a planet anymore but its a dwarf planet.
