Answer

Brief Explanations:

The widely - accepted theory of solar system formation is the nebular hypothesis. An interstellar cloud (nebula) of gas and dust was drawn together by gravitational forces. The central part of the collapsing cloud formed the Sun, and the surrounding material formed planets, moons, asteroids, etc. Option A is not consistent with the formation theory as a star - asteroid collision is not how the solar system formed. Option C is also incorrect as the merger of two stars is not the mechanism for solar system formation.

Answer:

B. An interstellar cloud was drawn together by gravity, forming planets, moons, and a star.
