Answer to Question 1

D

Answer to Question 2

If Pluto were to be considered a major planet, then many Kuiper Belt Objects are almost as big as Pluto, also orbit the Sun, some of them have moons also, and most are in more circular orbits closer to the ecliptic, behaving more like planets than Pluto does. Should they not also have been counted as planets as well?
