Your answer: —  Â·  Correct: D
Explanation

The Nebular Hypothesis, proposed by Immanuel Kant and refined by Pierre-Simon Laplace in 1796, posits that the solar system originated from a slowly rotating, cooling, and shrinking cloud of gas and dust [2]. As the nebula contracted due to gravity, it began to rotate more rapidly to conserve angular momentum, causing it to flatten into a disk shape. While the central mass condensed to form the proto-Sun, centrifugal forces caused the nebula to shed successive rings of material [2]. These rings of gas and dust eventually cooled and condensed through accretion to form the planets and their satellites, which continue to revolve in orbits around the central Sun [1][2]. Modern revisions by Schmidt and Weizscker further detailed how friction and collisions within this disk-shaped cloud facilitated the formation of planets from the dust and gas [1][2].
