A particular person is wearing a gold ring. Could this gold have any connection with neutron stars?
A)   No, we do not expect neutron stars to eject any significant amount of material into the Galaxy.
B)   Yes, some of the gold may have been created in collisions between neutron stars in binary systems.
C)   No, some of the hydrogen in the Earth's water may have been ejected from neutron stars as high-energy protons, but all heavy elements come from supernova explosions of normal stars.
D)   Yes, the neutrons in the gold nuclei were very likely ejected from neutron stars.
