ZnS exists in two crystalline structures. Mark the correct statement about their structures.

A)  In zinc blende, \[{{S}^{2-}}\]ions are arranged in ccp while \[Z{{n}^{2+}}\] ions occupy half of the tetrahedral sites.

B)  In zinc blende, \[{{S}^{2-}}\] ions are arranged in hcp and \[Z{{n}^{2+}}\]ions occupy all octahedral voids.

C)  In Wurtzite structure, \[{{S}^{2-}}\] ions are arranged in ccp and \[Z{{n}^{2+}}\] ions occupy half of tetrahedral voids.

D)  In Wurtzite structures, \[{{S}^{2-}}\]ions are in hcp arrangement and \[Z{{n}^{2+}}\]ions are occupying all octahedral voids.
