Solution

The correct options are
A Packing in second case is more effective.
C The stacking of layer on first type packing produces simple cubic structure.
D The ratio of coordination number for a sphere in first case to that in second case is $$2 : 3$$.
In square close packing, coordination number $$= 8$$, whereas in hcp, coordination number $$= 12$$. So, the ratio is $$2 : 3$$.
