Which of the Following Statements Correctly Describes the CsCl Structure

Multiple Choice

Which of the following statements correctly describes the CsCl structure type?

A) CsCl structure is composed of primitive cubic lattice of Cl^- anions with Cs⁺ cations occupying every cubic hole resulting in 8:8 cation : anion coordination.
B) CsCl structure is essentially body-centred cubic lattice with alternating Cl^- and Cs⁺ ions resulting in 8:8 coordination.
C) CsCl structure is composed of hexagonal close-packing of Cl^- anions with Cs⁺ cations occupying every octahedral hole, this arrangement of cations and anions results in a 6:6 cation : anion coordination.
