Explanation:

 

• The second layer of the sphere is placed on the first layer in the stacks of the depression.
• The second layer covers all the octahedral holes.
• The holes in the second layer are not in line with those in the first layer.
• If there is a third layer, it will cover the holes of the second layer.
• The arrangement will be ABC.
