Answer:
The correct answer is A. Dwarf planets orbit the Sun.
Explanation:
A dwarf planet is in direct orbit around the sun. Pluto cannot collide with Jupiter of their distance from the sun, meaning they are very far away from each other for a possible collision, however Pluto could collide with Neptune.
Dwarf planets are not really round, they assume a nearly round shape which is nearly hydrostatic equilibrium. Most assume a oval or elliptical shape
Eris cannot collide with Uranus. They don't even share the same orbit and are very far apart. Eris orbits the sun in 557 Earth years while Uranus does that in only 84 earth years.
