D.
A diamagnetic ion will have no unpaired subshells in its atomic orbitals. A paramagnetic ion will have one unpaired electron in its atomic orbitals, leading it to be slightly more magnetic due to the unbalance. For example, Zn2+ will lose 2 electrons from the 4s2 while leaving the 3d10 orbital full, leaving no unpaired electrons. Copper will lose electrons from the 4s2 orbital to fill the 3d10 orbital, a more stable configuration and thus a diamagnetic compound.
