According to our theory of solar system formation,what three major changes occurred in the solar nebula as it shrank in size?
A)It got hotter,its rate of rotation increased,and it flattened into a disk.
B)Its mass,temperature,and density all increased.
C)It gained energy,it gained angular momentum,and it flattened into a disk.
D)Its gas clumped up to form the terrestrial planets,nuclear fusion produced heavy elements to make the jovian planets,and central temperatures rose to more than a trillion Kelvin.

According to the theory of solar system formation, as the solar nebula shrank in size, it got hotter, its rate of rotation increased, and it flattened into a disk due to conservation of angular momentum. Option B is incorrect because the density would have decreased as the nebula expanded, not increased. Option C is incorrect because gaining energy and angular momentum would have been a result of the changes, not a cause. Option D is incorrect because although gas clumped up to form the terrestrial planets and nuclear fusion produced heavy elements to form the jovian planets, the central temperatures did not rise to more than a trillion Kelvin.
