which event led to the formation of our solar system?\na galaxy broke apart.\na massive star exploded.\na…

Answer:

C. A solar nebula collapsed.

Brief Explanations:

The widely - accepted theory for the formation of the solar system is the nebular hypothesis. According to this, a rotating cloud of gas and dust called a solar nebula collapsed under its own gravitational force. This led to the formation of the Sun at the center and the planets and other solar system bodies from the remaining material. A galaxy breaking apart is not related to solar system formation. A massive star explosion (supernova) can trigger star - formation but is not the direct cause of solar system formation. Dark matter does not directly materialize to form the solar system.
