The \[{{r}_{+}}/{{r}_{-}}\] ratio of \[ZnS\] is 0.402. Pick out the incorrect statements from the following?

A. \[ZnS\] is 4:4 coordination compound.
B. \[ZnS\] does not crystallize in rock salt type lattice because \[{{r}_{+}}/{{r}_{-}}\] is too small to avoid overlapping of \[{{S}^{2-}}\] ions.
C. \[Z{{n}^{2+}}\] ion is too small to fit precisely into the octahedral voids of \[{{S}^{2-}}\] ions.
D. \[Z{{n}^{2+}}\] ion is too large to fit into the octahedral voids of \[{{S}^{2-}}\] ions.
