The r+/r- ratio of ZnS is 0.402. Pick out the false statements of the following

A
ZnS is 4: 4 coordination compound.
B
ZnS does not crystallize in rock salt type lattice because $r_{+} / r_{-}$ s too small to avoid overlapping of $S^{2 -}$ ions
C
${Zn}^{2 +}$ ion is too small to fit precisely into the octahedral voids of S^2-ions
D
${Zn}^{2 +}$ ion is too large to fit into the octahedral voids of S^2- ions.

Zn²⁺ ion is too small to fit into the octahedral voids of S²⁻ ions.
