Zinc sulphide exists in two different forms-zinc blende and wurtzite. Both occurs as 4:4 coordination compounds. Choose the correct option from among the following :

Zinc blende and wurtzite are two distinct types of ZnS that can be found. Both exist in the form of 4:4 coordination compounds. Wurtzite has a hcp structure, while zinc blende has a fcc structure.
In zinc blende, ${\mathrm{S}}^{2-}$ ions alternate with ${\mathrm{Zn}}^{2+}$ ions in tetrahedral voids to produce a fcc unit cell.
In wurtzite, ${\mathrm{Zn}}^{2+}$ ions and ${\mathrm{S}}^{2-}$ ions combine to create a hcpc unit cell in alternating tetrahedral voids.
