Solution
The correct option is A12 When Zinc is converted from it's melted state to solid state, it has HCP structure.
In hcp lattice,
Each sphere touches 6 spheres in its layer and 3 spheres below the layer and 3 spheres above the layer; i.e. number of nearest neighbours are 12. Other examples are:Mg,Cd,TiandBe
Hence, option (c) is the correct answer.
