A nebula is the first step in the formation of the solar system

Answer: Option B

Explanation:

Solar system was formed several years ago from a solar nebula. A nebula is nothing but a cloud of dust and gas. The nebula was acted upon by the gravity. This led to the collapse of the nebula and it started to spin with all its materials in it.

As the spinning increased, more and more small particles were drawn in and bound by the ''force of gravity''. This resulted in the formation of a ''star'' and ''disk material'' for the formation of planets.
