Answer:
Hi there!
The correct answer will be: C. Pluto’s orbit crossed over the orbit of another planet.
Explanation:
When determining whether a planet is planet the IAU stated the planet must (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydro-static equilibrium (nearly round) shape, and (c) has cleared the neighborhood around its orbit. For poor Pluto's case he did not clear part (c).
