Which species does not exist?

Question

Which species does not exist? (A)  (SiCl6)2-  (B)  CCl62-  (C)  GeCl62-  (D)  AlCl4-

CCl62- does not exist. The reason is that carbon has no d-orbital, hence it cannot combine with 6 chlorine-atoms. All others (Si, Ge and Al) have d-orbital, hence form the given ions.
