The correct answer is the option C - HCP and CCP.
HCP and CCP are both Face-Centred Cubic (FCC) structures which have closely packed particles. They have a high packing efficiency compared to the other structures like the BCC and the simple cubic structures.
There are two types of voids in the HCP and the CCP. They are the tetrahedral and the octahedral voids. They are identical in both these structures because the voids are formed in between the 2 layers of the atoms.
