Answer:
The most efficient packing is present in (b)
hcp and ccp.
Explanation:
'hcp' stands for Hexagonal Close Packing and 'ccp' stands for Cubic Close Packing.
Packing efficiency can be defined as the percentage of total filled spaces by the particles in a crystal lattice.
It can be determined as-
[( Volume occupied by four spheres in a given unit cell)/ Total volume of the same unit cell] × 100
The packing efficiency has been found to be the highest in case of hcp and ccp.
