Which of the following is FCC:
Correct answer: D. None of these
- A. Zn
- B. Cd
- C. Mg
- D. None of these
Explanation
Zn, Cd and Mg all crystallize in Hexagonal ClosedPacking(HCP) structurehence none of these represent Face Centered Cubic (FCC).

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
