Solution

The correct options are
A the same co-ordination number.
C the same packing fraction.
The HCP and CCP structure has the same co-ordination number (12) and the same packing fraction (0.74) but different density as no of atoms as well as volume of cells is different.

Hence, the correct options are $A$ 4 and $C$
