According to our theory of solar system formation, why does the Sun rotate slowly today?
A) The Sun once rotated much faster, but it transferred angular momentum to charged particles caught in its magnetic field and then blew the particles away with its strong solar wind. B) The Sun once rotated much faster, but it transferred angular momentum to the planets during the parts of their orbits where they come closest to the Sun. C) The Sun once rotated much faster, but it lost angular momentum due to internal friction. D) The Sun once rotated much faster, but it lost angular momentum because everything slows down with time. E) The Sun was born rotating slowly because the solar nebula had very little angular momentum.
