Answer:

b. is a <u>scientific idea about the origin of our Solar System</u>

Explanation:

  • The nebular hypothesis provides the fact that the sun, stars, and all planets were formed from the same amount of dust and gas that shaped the earth some 4.5 billion years ago.
  • According to the nebular hypothesis, a star forms a dense and massive cloud of molecular hydrogen and then due to gravitationally unstable matter rotates, collapses and then forms a star.  
  • This star formation process naturally results in a disk of accelerated concluded by a gaseous tail. The formation of rocky planets was a result of the solar nebular disk model with the movement of the protoplanetary disks.
