Answer to Question 1

D

Answer to Question 2

The difference is that the comets in the Kuiper belt have not been scattered out by gravitational interactions with giant planets. Kuiper-belt comets formed beyond the orbit of Neptune in the flattened solar nebula and their orbits have not been greatly changed. Oort-cloud comets, however, formed within the orbit of the jovian planets and have been scattered out (or impacted other bodies in the solar system). The scattering was random so the orbits are in every direction and inclination, resulting in a spherical Oort cloud.
