A new star is forming inside this glowing cloud of gas. The dark band in the middle is made of a disk of thick dust, which obscures the light within it and hides the forming star from view. Newly forming stars are surrounded by gas and dust. Based on this observation--and your previous observations about the relative orbits, positions, and sizes of the planets--what is the most likely scenario for the formation of the Solar System?
Choose one:
A. A cloud of gas and dust collapsed into a spherical shape, within which the Sun and planets formed.
B. Two stars collided and broke apart to form the Sun and the planets.
C. A cloud of gas and dust collapsed into a flattened disk, within which the Sun and planets formed.
D. The Sun formed by itself from a collapsing cloud of gas and dust, then later gravitationally captured the planets as they happened to pass by.
