A) are confined to distances closer to the Sun than the orbit of Pluto and are mostly in the ecliptic plane.
B) can extend far beyond the orbit of Pluto and are primarily in the ecliptic plane.
C) are confined to distances closer to the Sun than the orbit of Pluto and are oriented randomly in the solar system.
D) can extend far out beyond the orbit of Pluto and can be oriented in any direction in the solar system.
