The 8:8 type of packing is present in option (a) CsCl (Caesium Chloride).
This is because it has a co-ordination number of 8. Therefore, its lattice also has a 8:8 structure. Co-ordination number can be described as the number of atom or ions which are immediately next to a central atom or ion in a crystalline structure.
Lattice structure is the structure of the “smallest unit of a crystal” which repeats itself to form the crystal.
