A student rubs an inflated balloon with wool. The student moves the balloon over bits of paper, and the balloon attracts it. Which statement best describes how the balloon models the early formation of planets in the solar system?

• The balloon and the planets are both constructed from bits of matter that they collect.

• The balloon circles over the bits of paper, just as the planets circle around each other.

• The balloon and the planets both display orbital motion around a larger body of mass.

• The balloon attracts bits of paper, just as the planets attract matter that is around them.
