The correct option is C ABC ABC ABC.....
The pattern of successive layers of ccp arrangement can be designated as ABC ABC ABC.....
ccp is cubic close packing. It is also called fcc (face centred cubic).In this packing, spheres of third layer are placed into octahedral voids.
Note:
When in ABC ABC ABC....., spheres of third layer are placed into tetrahedral voids, the packing is hcp (hexagonal close packing).
