Total number of octahedral void(s) per atom in a cubic closed pack structure The total number of octahedral void(s) per atom present in a cubic closed pack structure is
(a) 1
(b) 2
(c) 3
(d) 4

I answered with (d), but the key on internet says it is (a). Please clarify the dispute.
Finally got it, it was a misunderstanding. I ignored to read the word ‘per atom’ in a hurry. So clearly the answer is 1.
