A. Face centered cubic structure
B. Body centered cubic structure
C. Simple cubic
D. Diamond cubic structure
Choose the correct answer from the options given below :

Show Hint

Even though diamond is the hardest natural material, its atomic structure is actually the least densely packed among common lattices (only 34% full space). Hardness comes from the immense strength of its covalent $sp^3$ bonds, not packing density!
