The intermetallic compound LiAg crystallizes in the cubic lattice in which both lithium and silver have a coordination number of eight. The crystal class is

Lithium and silver both have a coordination number of eight in the cubic lattice in which the
intermetallic compound Li–Ag crystallizes. Body-centered cubic is the crystal class.
Simple cubic, body-centered cubic, hexagonal-close packing, and face-centered cubic all
have coordination numbers of 6, 8, 12, and 12 respectively.
Hence, the correct option is option (B) Body-centered cubic.
